> 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: https://issues.apache.org/jira/browse/ZOOKEEPER-442
