James Clampffer updated HDFS-10441:
-----------------------------------
Attachment: HDFS-10441.HDFS-8707.009.patch
Now using the default RPC delay as the failover delay to prevent this from
thrashing between datanodes that happen to both be marked standby while in the
middle of failing over. Ready for review, I plan on adding the exponential
backoff failover delay in another patch.
