Subject [jira] [Created] (HDFS-7786) Handle failures and slow writers for DFSOutputStream when there're multiple data streamers

---------------------------

             Summary: Handle failures and slow writers for DFSOutputStream when there're multiple
data streamers
                 Key: HDFS-7786
                 URL: https://issues.apache.org/jira/browse/HDFS-7786
             Project: Hadoop HDFS
          Issue Type: Sub-task
            Reporter: Li Bo
            Assignee: Li Bo
             Fix For: HDFS-7285


There're multiple data streamers in DFSOutputStream if it is used to write a striping layout
file. These streamers may have different write speed, and some may write data very slowly.
Some streamers may fail and exit. We need to consider these situations and give reliable handling.
