Summary: Utility to trigger heartbeat and wait until BP thread
queue is fully processed
Key: HDFS-16938
URL: https://issues.apache.org/jira/browse/HDFS-16938
Project: Hadoop HDFS
Issue Type: Improvement
Reporter: Viraj Jasani
Assignee: Viraj Jasani
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.
