I'd like you to reexamine a change. Please visit
http://gerrit.cloudera.org:8080/19608
to look at the new patch set (#11).
Change subject: [master] Exclude tservers in MAINTENANCE_MODE when leader
rebalancing
......................................................................
[master] Exclude tservers in MAINTENANCE_MODE when leader rebalancing
Currently, auto leader rebalancing may transfer new leaders to tservers
which have entered MAINTENANCE_MODE. Because a tserver in MAINTENANCE_MODE
is being maintained by administrators, maybe it is decommissioning.
Since it might be decommissioned/decommissioning, it doesn't make sense
for the leader rebalancer to transfer a leader to a tserver in MAINTENANCE_MODE
as leaders serve many users' requests. For this reason, we should exclude
such tservers.
This patch fixes the problem and adds an unit test for this.
