Subject [jira] [Commented] (HDFS-2863) Failures observed if dfs.edits.dir and shared.edits.dir have same directories.
Date Thu, 02 Feb 2012 23:36:53 GMT

    [ https://issues.apache.org/jira/browse/HDFS-2863?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13199365#comment-13199365

Aaron T. Myers commented on HDFS-2863:

Thanks for adding the test. A few small comments:

# No need for the "joiner" variable - it's only used once.
# I think "TestFSNamesystem" isn't a very good name for this test, since this really only
tests a very specific part of HA configuration. Perhaps just add this test case to TestHAConfiguration?
# Since we currently only support a single shared edits dir, the test could be made more realistic
by not configuring several.

> If same edits directory is configured in twice, both are treated independently. Edit
log roll is called on the same directory twice causing exceptions.
