Ravi Prakash commented on HDFS-11528:
-------------------------------------
Thanks for the report tangshangwen! I see the code has changed a little bit
https://github.com/apache/hadoop/blame/trunk/hadoop-hdfs-project/hadoop-hdfs/src/main/java/org/apache/hadoop/hdfs/server/namenode/FSDirAttrOp.java
in trunk. Are you able to load the namespace on a single node hadoop cluster
to see if this happens on trunk? Are you able to debug why this is happening?
