Error after bin/pio-start-all

[Vihang Mirkhelkar]

Hello,

Here are a list of errors I am getting after I hit the command pio-start-all 

It says starting HBase and then it gives the following errors:

Exception in thread "main" java.lang.UnsupportedClassVersionError: org/elasticsearch/bootstrap/Elasticsearch : Unsupported major.minor version 51.0

Exception in thread "main" java.lang.UnsupportedClassVersionError: org/apache/hadoop/hbase/util/HBaseConfTool : Unsupported major.minor version 51.0

Exception in thread "main" java.lang.UnsupportedClassVersionError: org/apache/hadoop/hbase/zookeeper/ZKServerTool : Unsupported major.minor version 51.0

Exception in thread "main" java.lang.UnsupportedClassVersionError: org/apache/hadoop/hbase/master/HMaster : Unsupported major.minor version 51.0

Exception in thread "main" java.lang.UnsupportedClassVersionError: org/apache/hadoop/hbase/regionserver/HRegionServer : Unsupported major.minor version 51.0

After that it shows the following:

Waiting 10 seconds for HBase to fully initialize...

Starting PredictionIO Event Server...

When I tried doing bin/pio status it:

ERROR] [Storage$] Error initializing storage client for source ELASTICSEARCH

[ERROR] [Storage$] org/elasticsearch/transport/ConnectTransportException : Unsupported major.minor version 51.0

Unable to connect to all storage backend(s) successfully. Please refer to error message(s) above. Aborting.

What is wrong in this. I did re-install it many times on Mac OS X Yosemite.

Kindly, help me  with this.

Thank-you.

Hi,

These errors are common if you only have Java 6 installed. You can verify your Java version by doing "java -version". If that's the case, please upgrade your Java to the latest version.

Regards,

Hello Donald Sir,

I have installed jre 8u45 right now. But when I type java -version from terminal it still shows

Am I doing something wrong ?

Kindly, help me with this as I have to show this in my school.

Thaking you.

Hello Sir,

 

Updated java version to 8 and yet it is giving the same error. Do I need to reinstall all dependencies ??

It is giving the following error:

Vihangs-MacBook-Air:~ vihangmirkhelkar$ java -version

java version "1.8.0_45"

Java(TM) SE Runtime Environment (build 1.8.0_45-b14)

Starting Elasticsearch...

Starting HBase...

Exception in thread "main" java.lang.UnsupportedClassVersionError: org/apache/hadoop/hbase/util/HBaseConfTool : Unsupported major.minor version 51.0

All other errors are the same.

Kindly, help me.

Thanking you.

Hello Sir,

I have installed java to new directory I guess. I created a link from old directory to new using the following command:

sudo ln -fs /Library/Internet\ Plug-Ins/JavaAppletPlugin.plugin/Contents/Home/bin/java /usr/bin/java

This was shown on Stackoverflow forum.

Do I need to install all dependencies again. Will the new path effect the re-installation?

Kindly, help me.

[Donald Szeto]

Have you restarted your Terminal session after installing Java 8 (from Oracle)? You shouldn't need to do anything extra to make it effective.

Regards,

Donald

(Copying back to the mailing list.)

Take a look at the file /Users/vihangmirkhelkar/PredictionIO/vendors/hbase-1.0.0/conf/hbase-env.sh. There should be a line where it sets the JAVA_HOME environmental variable. From your installation log it is pointing to Java 6. Please change it to point to Java 8 and try again.

Unless you have a need of Java 6, it is recommended that it be uninstalled because it is not supported by Oracle anymore.

Regards,

Donald

Hello Sir,

I have used the common bin/pio-start-all after restarting the terminal. I have attached the following errors using a screen shot. Kindly, let me know what you make of it.

Please help me as I am confused.

Thanking you.

Please use reply all so that the mailing list is copied and the community could benefit from the solution.

It looks like you are on a Mac system. You can get the correct path by doing "/usr/libexec/java_home -v 1.8" in the terminal. Java applet plugin is not a full JRE/JDK and will not work.

Donald

Hello Donald Sir,
I went into system preferences and in java control panel I came across this path :
/Library/Internet Plug-Ins/JavaAppletPlugin.plugin/Contents/Home/bin/java
Is this the path I need JAVA HOME to be pointing it to ?

Kindly, help me.

Thanking you.

Hello Sir,

I have found Environment Variables at that location. I have attached a screenshot. Kindly let me know what path to give as I am unable to find path for JAVA 8.

[Donald Szeto]

Did the command "/usr/libexec/java_home -v 1.8" not showing anything?

[Vihang Mirkhelkar]

Hello Sir,

It displays the following:

Vihangs-MacBook-Air:~ vihangmirkhelkar$ /usr/libexec/java_home -v 1.8

Unable to find any JVMs matching version "1.8".

No Java runtime present, try --request to install.

Kindly, help me.

Thanking you.

Please make sure you are installing the latest JDK 8 from this link: http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html and try /usr/libexec/java_home -v 1.8 again.

Regards,

Donald

[Vihang Mirkhelkar]

Hello Sir,

Installed it from the above link and I got the following :

Vihangs-MacBook-Air:~ vihangmirkhelkar$ /usr/libexec/java_home -v 1.8 

/Library/Java/JavaVirtualMachines/jdk1.8.0_45.jdk/Contents/Home

Vihangs-MacBook-Air:~ vihangmirkhelkar$ 

Now, what next should I do.

[Donald Szeto]

You have gotten exactly what you need. Just paste this value to replace the current value of JAVA_HOME in hbase-env.sh and you should be good to go.
