Subject [jira] [Updated] (HDFS-7095) TestStorageMover often fails in Jenkins
Date Sat, 20 Sep 2014 01:09:36 GMT

     [ https://issues.apache.org/jira/browse/HDFS-7095?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

Jing Zhao updated HDFS-7095:
    Attachment: HDFS-7095.000.patch

Initial patch. Instead of writing data to use all the DISK/ARCHIVE storage, the patch directly
sets the capacity of corresponding volumes to 0.

Also fixed NPE in Mover exposed by the new test: when a storage's remaining capacity is not
greater than 0, we can still use it as Source but avoid it using it as Target.

> TestStorageMover somehow often fails in Jenkins such as [build #8104|https://builds.apache.org/job/PreCommit-HDFS-Build/8104//testReport/org.apache.hadoop.hdfs.server.mover/TestStorageMover/].
> In testNoSpaceDisk, all DISK storage has remaining=0 so that it cannot create any hot
> We cannot reproduce it locally even Jing has run it for 100 times.
