Suresh Srinivas created HDFS-5986:
-------------------------------------
Summary: Capture the number of blocks pending deletion on namenode
webUI
Key: HDFS-5986
URL: https://issues.apache.org/jira/browse/HDFS-5986
Project: Hadoop HDFS
Issue Type: Bug
Components: namenode
Reporter: Suresh Srinivas
When a directory that has large number of directories and files are deleted,
the namespace deletes the corresponding inodes immediately. However it is hard
to to know when the invalidated blocks are actually deleted on the datanodes,
which could take a while.
I propose adding on namenode webUI, along with under replicated blocks, the
number of blocks that are pending deletion.
