Subject [jira] [Commented] (HBASE-4718) Backport HBASE-4552 to 0.90 branch.
Date Wed, 02 Nov 2011 23:39:32 GMT

    [ https://issues.apache.org/jira/browse/HBASE-4718?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13142691#comment-13142691

Jonathan Hsieh commented on HBASE-4718:
---------------------------------------

Here are the results of the relevent unit tests running tests on 0.90.x.  I'm fairly confident
that only known flakies could fail on the full run, will post any anomalies.

{code}

~/proj/hbase-0.90$ mvn test -Dtest=TestLoadIncrementalHFilesSplitRecovery,TestHRegionServerBulkLoad

....

> In discussion of HBASE-4552 / HBASE-4677 there has been some discussion about whether
and how to backport HBASE-4552 to the 0.90 branch.  This is a potentially compatibility breaking
so several approaches hav ebeen suggested.
> 1) provide patch but do not integrate
> 2) integrate patch that extends and deprecates old api without removing old api.  It
has been argued that  clients are supposed to use LoadIncrementalHFiles api and not at the
internal HRegionServer RPC api.
