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?) > Support read when a EC file is being written > -------------------------------------------- > > Key: HDFS-7661 > URL: https://issues.apache.org/jira/browse/HDFS-7661 > Project: Hadoop HDFS > Issue Type: Sub-task > Reporter: Tsz Wo Nicholas Sze > Assignee: GAO Rui > Attachments: EC-file-flush-and-sync-steps-plan-2015-12-01.png, > HDFS-7661-unitTest-wip-trunk.patch, > HDFS-EC-file-flush-sync-design-version1.1.pdf > > > We also need to support hflush/hsync and visible length. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
