error connect tasktracker for jobtracker
----------------------------------------
Key: MAPREDUCE-2444
URL: https://issues.apache.org/jira/browse/MAPREDUCE-2444
Project: Hadoop Map/Reduce
Issue Type: Bug
Components: tasktracker
Affects Versions: 0.20.1
Reporter: Alexey Diomin
In TaskTracker.java on create connection to JobTracker we check compare build version
if(!VersionInfo.getBuildVersion().equals(jobTrackerBV))
but
public static String getBuildVersion(){
return VersionInfo.getVersion() +
" from " + VersionInfo.getRevision() +
" by " + VersionInfo.getUser() +
" source checksum " + VersionInfo.getSrcChecksum();
}
in result identical version/revision/srcChecksum but compiled different users incompatible

------------------------------------------
we have error when build cluster with mixed distr (debian, centos).
source build by different users in result cluster not started
may be more correctly compare (version && revision && srcChecksum), not a build version string?
