Rushabh S Shah commented on HDFS-9653:
--------------------------------------

If the clients are upgraded  and the namenode is not upgraded and if we issue 'hdfs dfsadmin
-report' command, then what will be the default value of Pending Deletion blocks ?

> HDFS-5986 adds *Number of Blocks Pending Deletion* on namenode UI and JMX, propose to
expose this from hdfs dfsadmin -report as well. This is useful when hadoop admin was not able
to access UI (e.g on cloud), he/she can directly use command to retrieve this information.
