Subject [jira] [Commented] (HDFS-8366) Erasure Coding: Make the timeout parameter of polling blocking queue configurable in DFSStripedOutputStream
Date Tue, 19 May 2015 08:06:00 GMT

    [ https://issues.apache.org/jira/browse/HDFS-8366?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14550006#comment-14550006

Li Bo commented on HDFS-8366:
-----------------------------

Hi, Nicholas
Different streamers may have different write speed, if one streamer is too slow, the leading
stream should not wait for its ended block forever. So does the retrieving of striped blocks.
This sub task just replaces the two constants(30 & 90) with configurable properties in
{{DFSStripedOutputStream#Coordinator}}.
