Subject [jira] [Created] (HDFS-9180) Update excluded DataNodes in DFSStripedOutputStream based on failures in data streamers
Date Wed, 30 Sep 2015 21:05:04 GMT
Jing Zhao created HDFS-9180:
-------------------------------

             Summary: Update excluded DataNodes in DFSStripedOutputStream based on failures
in data streamers
                 Key: HDFS-9180
                 URL: https://issues.apache.org/jira/browse/HDFS-9180
             Project: Hadoop HDFS
          Issue Type: Sub-task
          Components: erasure-coding
    Affects Versions: 3.0.0
            Reporter: Jing Zhao
            Assignee: Jing Zhao


This is a TODO in HDFS-9040: based on the failures all the striped data streamers hit, the
DFSStripedOutputStream should keep a record of all the DataNodes that should be excluded.

This jira will also fix several bugs in the DFSStripedOutputStream. Will provide more details
in the comment.
