Subject [jira] [Commented] (ACCUMULO-2264) KilledTabletServerSplitTest fails on Hadoop2
Date Tue, 28 Jan 2014 06:32:39 GMT

    [ https://issues.apache.org/jira/browse/ACCUMULO-2264?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13883812#comment-13883812
] 

Sean Busbey commented on ACCUMULO-2264:
---------------------------------------

I think this points to an underlying problem with the tserver wal configuration. Hadoop can
be configured to set an arbitrary minimum blocksize (the property is dfs.namenode.fs-limits.min-block-size).

The tserver should probably be checking for this and then either issuing a WARN/ERROR to the
client and using the minimum or failing loudly and refusing to start.

> KilledTabletServerSplitTest tries to set tserver.walog.max.size to 50K which will cause
infinite loop as Hadoop won't create files with a blocksize less than 1M by default in 2.2.0
