Presto Error Codes

[Manases Blakemore]

Each connector is allocated its own 16-bit range of error codes, indicated in the table below. New allocations may be reserved by adding them to the table. In this document, a range such as 0x1234 represents 0x12340000 to 0x1234FFFF.

Additionally, the range 0x7F00 to 0x7FFF is reserved for private connectors. This is useful for connectors that are private to an organization (and thus will not conflict with other private connectors in other organizations).

When using the presto connector on the Qlik Sense Enterprise, after select Database and Owner, return the message:
"Unable to get tables list from the database: ERROR [HY000] [Qlik][Presto] (1050) JSON parsing error: 3." and don't list the tables list.

Verify the connection details: Double-check that the database and owner information you entered in the Presto connector settings are correct. Ensure that you have the necessary permissions to access the specified database.

Check the compatibility: Make sure that the version of Presto you are using is compatible with the version of the Presto connector in Qlik Sense Enterprise. Check the documentation or release notes for any known compatibility issues.

Review the connection settings: Go through the connection settings in the Presto connector Pay My Doctor Login and ensure that all the required parameters, such as host, port, username, password, etc., are correctly configured.

Test the connection: Use external tools or command-line utilities to verify if you can connect to the Presto database using the provided connection details. This step will help determine if the issue is specific to Qlik Sense or related to the database itself.

Update Qlik Sense and the connector: Ensure that you are using the latest version of Qlik Sense Enterprise and the Presto connector. Upgrading to the latest versions might resolve any known issues or bugs.

Consult Qlik Support: If the issue persists, it's recommended to reach out to Qlik support for further assistance. They can provide you with specific guidance based on the version and configuration of your Qlik Sense deployment.

I am hoping that someone may have run into this issue or have found some information regarding this problem some where on the web. I have searched high and low but I cannot find an exact match to the problem I had. Here is the story...

The only way to get the shutter to close is to turn the camera off. I take lens off flash off. Reattached everything turn camera on and I get the Error 80 on the top LCD. So I continue with my back up camera.

Once I get a break I go back to my bag, turn camera back on and I still get the Error 80. Then I decided to take the batteries out of the battery grip and I left it for 10 seconds put them back in and hey presto, errors gone and its back to normal.

Direct from a source at Canon, we have the basics to shed at least a tiny bit of light on the various error codes Canon is using for the 5D Mark II and beyond. While none of these error codes reveal enough information to allow you to do repairs on your own, any amount of information can be comforting when dealing with these errors if they occur.

I have had that error code with a 7d and had a variety of fixes. Errors tend to revolve around communictaion issues between camera and lens. One version was resolved with a thorough clean, another was a problem with the focus drive in the lens itself whihc had to be replaced.

I have also had a version where the camera freezes with no error codes - canon tell me that this may be a fault with the miror box and costs $600. It hasnt happened in the last 800 photos so I haven't worried about fixing it yet.

Hi, I have just had this error message appear on my new 5D Mk II. I was trying out live view and after it had been on for a while I got some bright white flashes across the screen then a lot of purple lines. Now the screen is mainly purple. By taking the battery out the error message goes away but the live view screen still has purple line on it.

I have a Pixma MX922 and I keep getting the error code 1660. I have changed the ink cartridge 3 times and keep getting the same error message. Is there anything I can do to to correct it or bypass this error? I would appreciate any suggestions.

Since you've already tried replacing the ink cartridge, the next step is to check the ink cartridge contacts. these are the small metal strips on the bottom of the ink cartridge that make contact with the printer. If they're dirty or damaged, the printer won't be able to detect the ink cartridge.

I have been replacing the ink cartridge several times, turning off and on and waiting, etc but I think biwek 86619 is on to something. Since this is yet another new Magenta cartridge, the contacts are factory fresh, but what about if there is a difficulty with the contacts in the magenta carrier where it must be seated?

If the printer is out of warranty, you would qualify for the Canon Upgrade program. This is for out of warranty units which have been diagnosed to require service or are incompatible with a new or upgraded system. This program allows you the opportunity to purchase a replacement product discounted from the list price. Free ground shipping is included with your purchase.

I noticed the chip on the cartridge was not the correct way around so the contacts were nit making contact. the chip can be easily prised off, turn it around push in back on the cartridge and hey presto contacts connected all ok

Had a useless chat on virtual assistant where they tell you to use the pull down menu on the printer screen - THERE IS NO PRINTER SCREEN AVAILABLE! Then was passed to a 'person' (that is not a person) and directed to download a driver for uploading a firmware update, Done and then it cant find my printer to perform the update because there is no communication and the printer is off-line, ARGH!

Same here. Got the error code to go away but scanner still doesn't work. Have spent three hours loading latest software, drivers, etc. to no avail. Printer and copier work, but not scanner. suspect some sort of firmware malfunction. Officejet Pro 8028. And no help from HP, I guess?

I deleted my driver and then couldn't download a new one! Somehow, finally I have got a case number and was able to contact a real person. When I called they said their server was down so please could I call tomorrow!!! I will let you know how I get on. This is the first time I have had a HP printer and I really am not very impressed so far...... Surely there should be a general fix by now?

I am all SORTED! After trying a few of the suggestions, virtual assist and the Whats App chat I got sent a tel number (from trouble shooting I think, spoke to an amazing technician and after 1 hour of phone call and video linking we got it sorted!

Been out today, was going to call help line. Pulled out the printer power supply - just for good measure- as that seemed to have some effect yesterday clearing the error message. Put it back in and hey presto everything seems to be working again.

launcher.log: There is a python process which starts the Presto process and the logs for that python process goes to thelauncher.log. If you do not find anything in the server.log, then next option is to see the launcher.log.

gc.log: This log is helpful in analyzing the cause for the long running job or for a query being stuck. This is quiteverbose so it can be helpful in looking at the Garabage Collection (GC) pause as a result of minor and full GC.

The query failure that occurs due to an exceeded maximum memory limit may be as a result of incorrect property valuesthat are overridden in the cluster. The values may not be required or the property names may have a typo/incorrectly entered.

When you get the Server did not reply exception, check the logs and look for the phrase SERVER STARTED. If thephrase is not in the logs, then there can be an error in the overridden Presto configuration on the cluster.

Ganglia is a monitoring system for distributed systems. You can access the Ganglia Monitoring page bynavigating to Control Panel > Clusters. Under the Resources column for the running cluster in question, thereis a Ganglia Metrics link. If that link does not exist, an administrator needs to enable it for the cluster in question.

Ganglia will provide visibility into many detailed metrics like presto-jvm.metrics, disk metrics, CPU metrics, memory metrics,and network metrics. It is very crucial in understanding system resource utilization during certain windows of time andtroubleshooting performance issues.

Understanding the Presto Metrics for Monitoring describes the list of metrics that can be seen on the Datadog monitoring service. Italso describes the abnormalities and actions that you can perform to handle abnormalities.

If the value of query.max-memory-per-node is set more than 42% of Physical Memory, cluster failures occur. For moreinformation, see the query execution properties table under Presto Configuration Properties.

Solution: This error occurs when the node bootstrap scripts of the cluster contain the presto server stop command.Otherwise, the scripts may have just caused the Presto server to abnormally shut down.

To resolve or avoid this error, run a node bootstrap script for Presto changes using the Qubole Presto Server bootstrap,which is an alternative to the node bootstrap. For more information, see Using the Qubole Presto Server Bootstrap.

There is no option to set endpoint url for minio. So currently not able to create any query on minio s3. This can be done by adding below code line in src/main/java/io/prestosql/plugin/tiledb/TileDBClient.java at 80 line
