Subject [jira] [Commented] (HBASE-7636) TestDistributedLogSplitting#testThreeRSAbort fails against hadoop 2.0
Date Fri, 12 Apr 2013 18:52:17 GMT

    [ https://issues.apache.org/jira/browse/HBASE-7636?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13630477#comment-13630477

Colin Patrick McCabe commented on HBASE-7636:

bq. Is HDFS-347 the "new" version?


bq. Is the current short circuit read (HDFS-2246?) in hadoop1 different from hadoop2's?

It's very similar.

bq. What is the fix version/target version for HDFS-347 – what HDFS branches are you targeting?

It's going to be merged to trunk at first.

bq. From HBase's point of view, this is purely a unit test fix and specifically for the MiniDFSCluster.
Do you think disabling the SCR feature for unit tests is a prudent idea?

If you are just trying to test functionality rather than performance, it's easiest to keep
it off.
