Yongjun Zhang updated HDFS-7226:
--------------------------------
Status: Patch Available (was: Open)
Submit patch 001.
HI [~jingzhao] and [~kihwal],
I found that the failure reported in this jira is also introduced by the
HDFS-7217 fix. But the issue took me some time to understand.
Basically, because of HDFS-7217 change, reporting of ReceivingBlock to NN is
delayed, in the reported testcase, they are replaced by ReceivedBlock later
(see comment in the comment I put in the patch).
Thanks Jing for the help on HDFS-7236. Would any of you please help taking a
look at the patch?
Thanks a lot.
