Hbase on Hadoop error

[Rimita Mitra]

Hi,

I am trying to run Hbase on a pseudo-distributed, single-node Hadoop cluster.
I am using hadoop 1.1.2 and Hbase 0.94.5.
The hadoop is running fine on the machine but whenever I try to start the Hbase

I get the following error

localhost: starting regionserver, logging to /usr/local/hbase/bin/../logs/hbase-tcs-regionserver-tcs-ThinkCentre-M92p.out

I dont know what I am doing wrong. Please help

Thanks

Hi Rimita,

I believe this line is the issue: <value>hdfs://master:54310/hbase </value>

And the error makes this clear: master: ssh: Could not resolve hostname master: Name or service not known

Instead of master, you need a valid hostname or IP address.  In your case since everything is on one node, you'll use localhost.

So like this: <value>hdfs://localhost:54310/hbase </value>

This is assuming you've verified that HDFS is on port 54310.  In my case it runs on port 8020 (Cloudera 4).

Bryan

[Rimita Mitra]

Thanks Bryan

The Hbase did start after the change but now I am facing a different problem.

The "zk_dump" is working properly but whanever I am trying to create a table (create 'test', 'cf')
from the ./bin/hbase shell, I am getting the following error.

 Failed setting up proxy interface org.apache.hadoop.hbase.ipc.HRegionInterface to localhost/127.0.0.1:60020 after attempts=1


I have made the following changes in the /conf/hbase-env.sh file
export HBASE_OPTS="-XX:+UseConcMarkSweepGC -Djava.net.preferIPv4Stack=true"

I donot have the permission to change the /etc/hosts file.

Please help!

Rimita

Hello Rimita

I haven't faced similar issue ever, but just by going through some of
the blogs, I guess the following:

* You are running hadoop & hbase cluster on an Ubuntu machine.
* If you can read the /etc/hosts, please verify if there is an entry
like this:
127.0.1.1 <hostname_of_machine>

If this is the case, then your hbase regionserver is listening on
127.0.1.1. You can verify this by using netstat command ( sudo netstat
-taupen | grep LISTEN )

* Solution: In your /etc/hbase/conf/hbase-site.xml file, specify
interfaces that will be used for master and regionserver explicitly.

<configuration>
<property>
<name>hbase.master.dns.interface</name>
<value>lo</value>
</property>
<property>
<name>hbase.regionserver.dns.interface</name>
<value>lo</value>
</property>
</configuration>

I think this should solve your problem. Please let me know if this
doesn't work.

Hi,

Thank you for the reply :-)

It did solve the problem but now I am getting a new error "Master not running".

I went to the Hadoop logs and both in the job tracker logs and namenode logs I found the following error

2013-05-07 14:58:12,795 ERROR org.apache.hadoop.security.UserGroupInformation: PriviledgedActionException as:tcs cause:java.io.IOException: File /app/hadoop/tmp/mapred/system/jobtracker.info could only be replicated to 0 nodes, instead of 1

java.io.IOException: File /app/hadoop/tmp/mapred/system/jobtracker.info could only be replicated to 0 nodes, instead of 1

I am very new to Hadoop and Hbase and have no idea why I am getting this error.
I also went through some of the blogs but nothing fruitful turned out.  :-( :-( :-(
Please Help!!!!

Hello Rimita

I have few questions for you:

1. First of all, why are you using mapreduce ?
2. Are you setting hadoop & hbase cluster for opentsdb ?
3. Have you started the hbase-master ? In case you did and it die
later, can you just copy paste the logs from the hbase-master log file.

I am also very new to hadoop, hbase and opentsdb world, but you need to
read to get the basic understanding about how everything is
inter-related.

Hi Pradeep,

Yes, I am setting up hadoop and hbase for Opentsdb and I want to use mapreduce.

The hbase-master log is as follows:-

Hello Rimita,

 Based on the hbase-master log which you pasted in the last mail, your hbase-master seems to be running properly.
 

It did solve the problem but now I am getting a new error "Master not running".

  

  Can you paste the logs where exactly you got this error.

I went to the Hadoop logs and both in the job tracker logs and namenode logs I found the following error

2013-05-07 14:58:12,795 ERROR org.apache.hadoop.security.UserGroupInformation: PriviledgedActionException as:tcs cause:java.io.IOException: File /app/hadoop/tmp/mapred/system/jobtracker.info could only be replicated to 0 nodes, instead of 1

2013-05-07 14:58:12,795 INFO org.apache.hadoop.ipc.Server: IPC Server handler 5 on 54310, call addBlock(/app/hadoop/tmp/mapred/system/jobtracker.info, DFSClient_NONMAPREDUCE_-252682707_1, null) from 127.0.0.1:60102: error: java.io.IOException: File /app/hadoop/tmp/mapred/system/jobtracker.info could only be replicated to 0 nodes, instead of 1

java.io.IOException: File /app/hadoop/tmp/mapred/system/jobtracker.info could only be replicated to 0 nodes, instead of 1

Basically this error comes if either of the following happens:

* Hadoop Datanode is not running. You can check whether is there any datanode connected to namenode or not either from namenode logs or by running the following command:

  $ sudo netstat -taupen | grep ESTABLISHED  | grep $(ps -ef | grep namenode | grep -v grep|  awk '{print $2}')

* In hdfs-site.xml, dfs.data.dir is not configured and its taking the default /tmp directory, which is cleared when the machine restart. In those cases also you will get the above error.

* There is some firewall active, which is blocking the connection. Since you are running in pseudo-distributed mode, I don't think this would be an issue. Please for safety, just checkout selinux settings and iptables rules.

Can you just post the output of the command so I can verify that everything is working properly:

$ sudo netstat -taupen | grep LISTEN
