Subject [jira] [Updated] (HDFS-4204) TestNNThroughputBenchmark fails in branch-1
Date Mon, 26 Nov 2012 19:51:00 GMT

     [ https://issues.apache.org/jira/browse/HDFS-4204?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Jing Zhao updated HDFS-4204:
----------------------------

    Attachment: HDFS-4204.b1.003.patch

The same test from HADOOP-8372 is also included. 

All the unit tests have passed except TestFileCreationNamenodeRestart, which should be unrelated
since it also fails without the patch. The test-patch result:
{noformat}
-1 overall.  
    +1 @author.  The patch does not contain any @author tags.
    +1 tests included.  The patch appears to include 3 new or modified tests.
    +1 javadoc.  The javadoc tool did not generate any warning messages.
    +1 javac.  The applied patch does not increase the total number of javac compiler warnings.
    -1 findbugs.  The patch appears to introduce 225 new Findbugs (version 2.0.1) warnings.
