Subject [jira] [Updated] (HDFS-7786) Handle slow writers for DFSStripedOutputStream
Date Wed, 01 Apr 2015 05:46:53 GMT

     [ https://issues.apache.org/jira/browse/HDFS-7786?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Li Bo updated HDFS-7786:
------------------------
    Description: The streamers in DFSStripedOutputStream may have different write speed. We
need to consider and handle the situation when one or more writers begin to write slowly.
 (was: 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. )
