Subject [jira] [Commented] (HBASE-7600) TestAdmin.testCreateBadTables is failing occasionally
Date Thu, 12 Dec 2013 20:13:07 GMT

    [ https://issues.apache.org/jira/browse/HBASE-7600?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13846690#comment-13846690
] 

Lars Hofhansl commented on HBASE-7600:
--------------------------------------

Actually this fix has an interesting side effect.
Sometimes an HBase cluster is wiped by just removing the HDFS data. If the ZK state stays
around we can now no longer create tables for which there exists a znode already. Before this
patch that was possible. So the element of surprised has increased.

> See in a 0.94 test run.
> Looks like in some cases it is possible to create two tables with the same name, which
is worrisome.
