-----------------------------------
Code Reviews are posted at : https://gerrit.cloudera.org/#/c/4099/
I also performed downgrade/upgrade of clusters as per [~adar]'s suggestion in
the review, here are the steps followed:
Start the cluster with 0.10.0 release:
- Picked a random test which creates a table and distributes the replica
evenly, test elects the master as leader
- Leave the FS layout files intact even after test is done(using flag
leave_test_files=always)
- Finish the test
Downgrade cluster 0.9.1 release:
- Start the cluster using same FS layout used earlier
- Started the master first, and then tservers, and also reversed the orders
in bringing up.
- Logs are attached as cluster-downgrade.log
- Kill the master/tservers instances
Upgrade back to 0.10.0 release:
- Start the cluster using same FS layout used earlier
- Started master first, and then tservers, and tried permutation/combo of
bringups in differenrt order.
- Logs are in cluster-upgrade.log
- Kill master/tservers
> expose software version in ListMaster RPC response

> KUDU-1490 exposed the software version of tablet servers in the
> GetTabletServers RPC response, but an equivalent doesn't exist for
> ListMasters response. This will become more important as multi-master setups
> get more common.
