Subject [jira] [Created] (HDFS-10425) Clean up NNStorage and TestSaveNamespace
Date Wed, 18 May 2016 12:16:12 GMT
Andras Bokor created HDFS-10425:

             Summary: Clean up NNStorage and TestSaveNamespace
                 Key: HDFS-10425
                 URL: https://issues.apache.org/jira/browse/HDFS-10425
             Project: Hadoop HDFS
          Issue Type: Sub-task
    Affects Versions: 0.23.0
            Reporter: Andras Bokor
            Assignee: Andras Bokor

This JIRA tracks a TODO in TestSaveNamespace. Currently, if, while writing the VERSION files
in the storage directories, one of the directories fails, the entire operation throws IOE.
This is unnecessary -- instead, just that directory should be marked as failed.

This is targeted to be fixed _after_ HDFS-1073 is merged to trunk, since it does not ever
dataloss, and would rarely occur in practice (the dir would have to fail between writing the
fsimage file and writing VERSION)
