Subject [jira] [Commented] (HDFS-8936) Simplify Erasure Coding Zone DiskSpace quota exceeded exception error message
Date Wed, 09 Sep 2015 03:24:45 GMT

    [ https://issues.apache.org/jira/browse/HDFS-8936?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14736082#comment-14736082
] 

Zhe Zhang commented on HDFS-8936:
---------------------------------

[~walter.k.su] What I'd like us to do is basically to move the NN-related logics ({{locateFollowingBlock}}
and {{bumpGenStamp}}) *up* to a coordinated level (either OutputStream or Coordinator or a
new class). If creating a {{BlockGroupDataStreamer}} class is easier than refactoring {{DFSOutputStream}}
then I'm +1 on the idea.

> When a EC directory exceed DiskSpace quota, the error message is along with DFSStripedOutputStream
inner exception message. Error messages should be as simple and clear as normal hdfs directory.
