Subject [jira] Commented: (HADOOP-5203) TT's version build is too restrictive
Date Wed, 25 Feb 2009 01:06:01 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-5203?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12676465#action_12676465

Runping Qi commented on HADOOP-5203:
------------------------------------


I prefer to provide options to allow the user to specify the fields of buildversion to be
compared.
The default option should be the same as it is now (all fields). But the user can, for example,
 specify to compare only the hadoop version numbers and revision numbers.

> 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).
