Description

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
