Subject [jira] [Commented] (HDFS-7661) Support read when a EC file is being written
Date Tue, 15 Dec 2015 00:37:46 GMT

    [ https://issues.apache.org/jira/browse/HDFS-7661?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15057063#comment-15057063

Zhe Zhang commented on HDFS-7661:

Thanks for the design Rui. I haven't finished reading it. But some quick comments below:
# Sorry I didn't get back to your above question in time. Yes I think we are already reading
the correct visible length for EC files, assuming no hflush.
# I guess we should rename this JIRA to "Support hflush/hsync"? Should also consider merging
it with HDFS-7691 ([~vinayrpet] are you still working on it?)
