Subject [jira] Commented: (HBASE-2233) Support both Hadoop 0.20 and 0.21
Date Wed, 17 Feb 2010 20:40:27 GMT

    [ https://issues.apache.org/jira/browse/HBASE-2233?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12834979#action_12834979

Jean-Daniel Cryans commented on HBASE-2233:
-------------------------------------------

bq. so - at its current stage of HBase trunk - what are the patches suggested/ advisable for
hdfs - 0.21 ?

None that I know of.

bq. what would be the similar patches ( if applicable) for hadoop 0.20.x as well ?

It's not all done yet but there's HDFS-200, HDFS-142 and one other that I don't remember.
Dhruba said he will tag them "hbase".

> Since Hadoop 0.21 isn't going to be well supported and that a lot of users may wish to
stick on 0.20, the next HBase major release should support both 0.20 and 0.21. 
> HDFS-265 support will be swapped for HDFS-200 if running on HDFS 0.20. A cluster without
that patchset shouldn't be supported.
