hadoop getProtocolVersion and getBuildVersion error
Hi, all. Today I noticed that my hadoop cluster (r0.20.0+jdk1.6) threw
some errors in RPC handling. Below is part of the content of namenode
log file:

I noticed that the similar error appears on the log in every datanode.
Can anybody tell me how to fix this?
I have patched this:
https://issues.apache.org/jira/browse/HADOOP-5139, but the error still
exist. I really don't know what to do and am expecting for your help!
Best regards,

Re: hadoop getProtocolVersion and getBuildVersion error
Posted by Starry SHI <st...@gmail.com>.
Hi, Jason. Your advice seems right, because there are several users in
my hadoop cluster. It is possible for some user to re-compile some
files in hadoop. Since I am new to hadoop, could you please tell me
how to restore the version so as to get rid of the exceptions?
Further, can you share with me how to avoid users to modify the hadoop
base files?
Eagering to hear your advice soon!!!
Thank you again for your kind help!
Best regards,
Starry

Re: hadoop getProtocolVersion and getBuildVersion error
Posted by jason hadoop <ja...@gmail.com>.
Most likely someone has compiled in your production hadoop tree.
The default is to include the build subdirectory in the classpath ahead of
the jars, and the compile process changes the version number.
I haven't looked at 0.20 but up through 0.19, src/saveVersion.sh handles
this.

Re: hadoop getProtocolVersion and getBuildVersion error
Posted by Abhishek Verma <ve...@gmail.com>.
Hi Starry,
I noticed the same problem when I copied hadoop-metrics.properties from my
old hadoop-0.19 conf along with the other files. Make sure you are using the
right version of the conf files.
Hope that helps.
