---------------------------------------
virajjasani opened a new pull request, #5445:
URL: https://github.com/apache/hadoop/pull/5445
As a follow-up to HDFS-16935, we should provide utility to trigger heartbeat
and wait until BP thread queue is fully processed. This would ensure 100%
consistency w.r.t active namenode being able to receive bad block reports from
the given datanode. This utility would resolve flakes for the tests that rely
on namenode's awareness of the reported bad blocks by datanodes.
