Description

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.
