Subject [jira] [Commented] (HBASE-5317) Fix TestHFileOutputFormat to work against hadoop 0.23
Date Mon, 06 Feb 2012 19:08:03 GMT

    [ https://issues.apache.org/jira/browse/HBASE-5317?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13201473#comment-13201473

Gregory Chanan commented on HBASE-5317:
---------------------------------------

@Ted:
I agree we shouldn't just catch the TableExistsException -- that's why I didn't initially
post that part of the patch.  My recollection of that issue was that the MiniMRCluster is
creating a "target" directory in hbase.rootdir [I could be wrong about the exact location].
 When we call "table.getTableDescriptor()" it can't get a table descriptor for "target", so
throws a TableExistsException.  Can the handleDeprecation call prevent the target directory
from being created?  Or are you thinking of something else?

It also seems a little strange to me that calling "table.getTableDescriptor();" tries to get
table descriptors for *everything* in hbase.rootdir.  Why should I get an exception thrown
if hbase can't find a TableDescriptor for "target" when I am only asking about "table"?
