Subject [jira] [Created] (HDFS-11534) Add counters for number of blocks in pending IBR
Date Wed, 15 Mar 2017 18:06:41 GMT
Xiaobing Zhou created HDFS-11534:

             Summary: Add counters for number of blocks in pending IBR
                 Key: HDFS-11534
                 URL: https://issues.apache.org/jira/browse/HDFS-11534
             Project: Hadoop HDFS
          Issue Type: Improvement
            Reporter: Xiaobing Zhou
            Assignee: Xiaobing Zhou

IBR can be sent in batch. For the sake of diagnosis, it's helpful to understand work load
of pending queue, e.g. how many blocks as total, how many blocks in status of RECEIVING_BLOCK,
RECEIVED_BLOCK, and DELETED_BLOCK, respectively. Also the metrics can be exposed to JMX.
