Subject [jira] [Commented] (HDFS-3948) TestWebHDFS#testNamenodeRestart occasionally fails
Date Fri, 26 Oct 2012 14:01:17 GMT

    [ https://issues.apache.org/jira/browse/HDFS-3948?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13484938#comment-13484938
] 

Hudson commented on HDFS-3948:
------------------------------

Integrated in Hadoop-Mapreduce-trunk #1237 (See [https://builds.apache.org/job/Hadoop-Mapreduce-trunk/1237/])
    HDFS-3948. Do not use hflush in TestWebHDFS.testNamenodeRestart() since the out stream
returned by WebHdfsFileSystem does not support it. Contributed by Jing Zhao (Revision 1402270)

     Result = FAILURE

> After fixing HDFS-3936 I noticed that TestWebHDFS#testNamenodeRestart fails when looping
it, on my system it takes about 40 runs. WebHdfsFileSystem#close is racing with restart and
resulting in an add block after the edit log is closed.
