Subject [jira] [Updated] (HBASE-9274) After HBASE-8408 applied, temporary test files are being left in /tmp/hbase-<user>
Date Wed, 21 Aug 2013 17:37:51 GMT

     [ https://issues.apache.org/jira/browse/HBASE-9274?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Jonathan Hsieh updated HBASE-9274:
----------------------------------

    Status: Patch Available  (was: Open)

The patch submitted makes it so that tests no longer drop detritus into /tmp/hbase-<user>.
 The root cause is that instances of a default HBaseConfiguration with hbase.rootdir set to
/tmp/hbase-<user> sneaks into different parts of test code via mocked or wrapped RegionServerServices
and FileSystems, and because the namespaces changes cause the hfile archiver to generates
dirs by consulting hbase.rootdir (instead of using a relative path like before).    The patch
makes it good style to instantiate hregions and other objects from the HBaseTestingUtility
helpers methods.
