Yiqun Lin commented on HDFS-11632:
----------------------------------
Thanks [~xyao] for reporting this.
I am thinking the root cause of this is that the cache blocks info is not
completely reported to namenode when Jenkins is busy. In addition, I see the
cache report interval time is 10s by default. So I think there is a chance to
cause the test failure.
Hi [~xyao], any comments for this? Will attach the patch after your further
comments. Thanks.
