Secondary NameNode doCheckpoint Exception

[Furkan Bıçak <bi...@gmail.com>]

Hi Everyone,

I am starting my hadoop cluster manually from Java which works fine 
until some time. When secondary NameNode tries to do merge it gives me 
the following exception:

---------------------------
13/10/03 10:29:38 ERROR namenode.SecondaryNameNode: Throwable Exception 
in doCheckpoint:
13/10/03 10:29:38 ERROR namenode.SecondaryNameNode:

Hi,

I have noticed that this exception occurs when I start the cluster from 
a JUnit test case. If the cluster is started from a main method, it 
doesn't give any exception at all. What may differ between these cases 
so that SecondaryNameNode cannot do the merge operation?

Thanks,

Frkn.

Re: Secondary NameNode doCheckpoint Exception

Hi,

Content of the VERSION file of NameNode is as follows:
-----------------------------------------------------
#Thu Oct 03 11:20:57 EEST 2013
namespaceID=1005981884
cTime=0
storageType=NAME_NODE
layoutVersion=-41
-----------------------------------------------------

However, I could not find any VERSION file for Secondary NameNode. Just 
to mention, I am using Pseudo-Distributed Mode.

Thanks.

Hi,

There is some layout Version value issue in your VERSION file. Can you
please share the VERSION file content from NN and SNN ?

${dfs.name.dir}/current/VERSION

Regards
Jitendra

Re: Secondary NameNode doCheckpoint Exception

[Furkan Bıçak <bi...@gmail.com>]

What I simply do is starting NameNode, DataNode, SecondaryNameNode, 
JobTracker and TaskTracker respectively. Why would SecondaryNameNode 
throws an exception when doing merge. Am I missing some configurations? 
Or how can I set checkpoint period?

Thanks,
Frkn.

Re: Secondary NameNode doCheckpoint Exception

[Furkan Bıçak <bi...@gmail.com>]

What I simply do is starting NameNode, DataNode, SecondaryNameNode, 
JobTracker and TaskTracker respectively. Why would SecondaryNameNode 
throws an exception when doing merge. Am I missing some configurations? 
Or how can I set checkpoint period?

Thanks,
Frkn.

When you said "started from java" does that means you are doing some
development work using eclipse and hadoop?

May be I'm not familiar with this kind of environment.

Re: Secondary NameNode doCheckpoint Exception

[Furkan Bıçak <bi...@gmail.com>]

I don't have any problem when starting and stoping the cluster with 
scripts. I am having this problem when starting the cluster from Java.

Also, when I start the cluster from Java, I can run map-reduce jobs and 
it succesfully finishes. However, after some time about 5 minutes when 
the secondary namenode is started, it tries the merge and then gives 
that error.

Thanks,
Frkn.

Re: Secondary NameNode doCheckpoint Exception

[Furkan Bıçak <bi...@gmail.com>]

I don't have any problem when starting and stoping the cluster with 
scripts. I am having this problem when starting the cluster from Java.

Also, when I start the cluster from Java, I can run map-reduce jobs and 
it succesfully finishes. However, after some time about 5 minutes when 
the secondary namenode is started, it tries the merge and then gives 
that error.

Thanks,
Frkn.

Re: Secondary NameNode doCheckpoint Exception

[Furkan Bıçak <bi...@gmail.com>]

Hi,

I have noticed that this exception occurs when I start the cluster from 
a JUnit test case. If the cluster is started from a main method, it 
doesn't give any exception at all. What may differ between these cases 
so that SecondaryNameNode cannot do the merge operation?

Thanks,

Frkn.

Hi,

There is some layout Version value issue in your VERSION file. Can you
please share the VERSION file content from NN and SNN ?

Re: Secondary NameNode doCheckpoint Exception

[Furkan Bıçak <bi...@gmail.com>]

Hi,

I have noticed that this exception occurs when I start the cluster from 
a JUnit test case. If the cluster is started from a main method, it 
doesn't give any exception at all. What may differ between these cases 
so that SecondaryNameNode cannot do the merge operation?

Thanks,

Frkn.
