Subject [jira] [Updated] (HDFS-1829) TestNodeCount waits forever, errs without giving information
Date Sat, 16 Apr 2011 23:59:05 GMT

     [ https://issues.apache.org/jira/browse/HDFS-1829?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Matt Foley updated HDFS-1829:
-----------------------------

    Attachment: 1829_TestNodeCount_v4.patch

I had originally rejected trying to factor out those similar-but-different loops, because
using callback objects would have increased the code complexity more than was worthwhile.
 However, you pushed me to look at it again, and there's a better solution :-)  Please see
if you agree.

> In three locations in the code, TestNodeCount waits forever on a condition. Failures
result in Hudson/Jenkins "Timeout occurred" error message with no information about where
or why. Need to replace with TimeoutExceptions that throw a stack trace and useful info about
the failure mode.
> Also investigate possible cause of failure.
