JT and TT should not have to match build versions
-------------------------------------------------
Key: MAPREDUCE-1817
URL: https://issues.apache.org/jira/browse/MAPREDUCE-1817
Project: Hadoop Map/Reduce
Issue Type: Bug
Components: tasktracker
Affects Versions: 0.20.2, 0.20.1, 0.20.3, 0.21.0, 0.22.0
Reporter: Eli Collins
Fix For: 0.22.0
TaskTracker#offerService checks for a match with the JT
VersionInfo#getBuildVersion, and fails if they are the same version but happen
to be built at a different time of day. It seems like the correct test is
VersionInfo#getRevision. fwiw the NN and DN do not have to match build
versions.
