[jira] Commented: (HBASE-854) hbase-841 broke build on hudson?

["Jim Kellerman (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/HBASE-854?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12627064#action_12627064 ] 

Jim Kellerman commented on HBASE-854:
-------------------------------------

I ran all tests locally. The ones that failed: TestCompaction, TestHRegion, TestSplit, TestMergeTool, TestMigrate all failed due to a change introduced by the patch for HBASE-826. The offending line is in HStore.compact:
{code}
    List<MapFile.Reader> copy = new ArrayList<MapFile.Reader>(pReaders.size());
    Collections.copy(copy, pReaders);
{code}

Couldn't the same effect be accomplished by the following single line?
{code}
    List<MapFile.Reader> copy = new ArrayList<MapFile.Reader>(pReaders);
{code}

> 841 changed interfaces.  Changed interfaces can make for odd issues like the hangs exhibited up on hudson (stuff is failing for me on my laptop since about the commit 841... timeouts.  I don't have same issue on branch).
