Subject [jira] [Updated] (HBASE-2233) Support both Hadoop 0.20, 0.21, and 0.22
Date Fri, 03 Jun 2011 23:54:47 GMT

     [ https://issues.apache.org/jira/browse/HBASE-2233?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

stack updated HBASE-2233:
-------------------------

    Attachment: 2233-v5.txt

All tests pass now building against 0.22 hadoop but with one kink. TestHFileOutputFormat fails
by hanging BECAUSE our avro is 1.4.1 but the avro in hadoop 0.22 is 1.3.2; when this test
runs IF YOU ENABLE MR DEBUG you'll see NoSuchMethodException thrown (Thanks to Todd for help
in here).  I'm tempted to cut avro from hbase core.

I am now testing hbase up on cluster.

Still to do is verify this patch passes all tests with hadoop 0.20 under it.

> 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.
