Subject [jira] [Commented] (HADOOP-5203) TT's version build is too restrictive
Date Fri, 06 Jan 2012 07:09:39 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-5203?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13181176#comment-13181176
] 

Matt Foley commented on HADOOP-5203:
------------------------------------

Note that the "Fix Version" is indeed correct; this patch was committed to trunk after the
0.20 branch point, so only v0.21 and higher have the fix.  HADOOP-7960 ports it to branch-1
so that v1.1 and higher will also have the fix.

> 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).
