Description

HBaseAdmin apis like tableExists(), flush, split, closeRegion uses catalog tracker. Every time Root node tracker and meta node tracker are started and a listener is registered. But after the operations are performed the listeners are not getting removed. Hence if the admin apis are consistently used then it may lead to memory leak.
