-----------------------------------
Hi Andrew,
I’m a newbie to apache community, HDFS-11303 is the first issue I've submitted
In last week, I received a mail said you updated this issue, thanks a lot for
your attention on this issue!
But the issue seems been frozen to me, I can’t do any operation on it now,
could you help point out what’s the status of this issue now, and what should I
do next?
Thanks a lot
Best
Chen
