Project: Accumulo
Issue Type: Improvement
Components: tserver
Affects Versions: 1.4.0
Reporter: Eric Newton

After running randomwalk test for several days, tablet servers began to run out
of memory. Heap dump analysis revealed a large number of HashMap entries.
Inspection of those entries found they were referenced by zookeeper watches. A
quick search finds this to be a known zookeeper issue:
