                 Key: HDFS-13027
                 URL: https://issues.apache.org/jira/browse/HDFS-13027

          Issue Type: Bug
          Components: namenode
            Reporter: Vinayakumar B


Since File deletions and Block removal from BlocksMap done in separate locks, there are possibilities of NPE due to calls of {{blockManager.getBlockCollection(block)}} returning null.

Handle all possibilities of NPEs due to this.
