Xiaoyu Yao commented on HDFS-11196:
-----------------------------------

Thanks [~anu] for the update. Patch v002 looks pretty good to me. +1 after the minor issue
below fixed.

TestContainerSmallFile.java Line 66: can we add check for {{cluster != null }}?

{code}
if (cluster != null) {
  cluster.shutdown();
}
{code}

This will fix the Jenkins issue like below:
{code}
