Subject [jira] Commented: (HADOOP-2737) HOD fails to allocate nodes if the hadoop version is a string ( e.g Hadoop full )
Date Wed, 30 Jan 2008 04:19:34 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-2737?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12563823#action_12563823
] 

Hemanth Yamijala commented on HADOOP-2737:
------------------------------------------

We only require the version to have a numeric major and minor version. The release / revision
can be anything. So 0.15.1-H2422-H2460 and 0.15.3-H2085 should both work correctly. However,
'hadoop-full' would not. 

I feel it is reasonable to expect a numeric major and minor versions, as that is the way most
version strings are built for any software, no ?
