Subject [jira] [Commented] (HBASE-5922) HalfStoreFileReader seekBefore causes StackOverflowError
Date Thu, 10 May 2012 18:10:55 GMT

    [ https://issues.apache.org/jira/browse/HBASE-5922?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13272571#comment-13272571

ramkrishna.s.vasudevan commented on HBASE-5922:
-----------------------------------------------

bq.@Stack what is the procedure for doing the back port to all the affected versions?
As Stack did not reply to this i can tell this.
Just create similar patches for different branches, like download the svn code and prepare
patches and again submit it in this JIRA.
Generally patches affecting across versions will be individually committed to all versions
with the respective patches prepared against the version.
Hope am clear.  Let me know if you have any questions.
