Subject [jira] Commented: (HADOOP-5203) TT's version build is too restrictive
Date Thu, 09 Apr 2009 07:44:12 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-5203?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12697422#action_12697422
] 

Rick Cox commented on HADOOP-5203:
----------------------------------

Tests with errors were TestMRServerPorts (appears to have encountered ports already in use)
and  TestQueueCapacities (capacity-scheduler, appears to have issues with file access and
locking), both of which are unlikely to be related to this patch.

> At start time, TT checks whether its version is compatible with JT.
> The condition is too restrictive. 
> It will shut down itself if one of the following conditions fail:
> * the version numbers must match
> * the revision numbers must match
> * the user ids who build the jar must match
> * the build times must match
> I think it should check the major part of the version numbers only (thus any version
like 0.19.xxxx should be compatible).
