-----------------------------------------------------------
Reproduced:
creating & deleting table continuously, the leader memory usage grows from xxMB
to xGB, and it will continues to grow. Kill the leader, another one becomes the
new leader which memory usage instantly grows to xGB.
e.g. 3411MB used by KuduMasterLeader, 2598MB consumed by
TabletLoader.VisitTablet, 1999MB by kudu.master.SysTabletEntryPB.MergeFrom
I'm wondering it's the normal impl or memory leak..

kill the leader, another one becomes leader and it;s memory usage becomes
instantly grows to xGB, most of it's memory usage is consumed in
TableLoader.VisitTable and TabletLoader.VisitTablet
I'm wondering it's the normal impl or memory leak..
