stack commented on HBASE-11887:
-------------------------------
OK. Let me commit. Its been running this last few hours w/o a full GC. I have
it set so a full GC kills the RS using below configs:
export SERVER_GC_OPTS="-verbose:gc -XX:PrintFLSStatistics=1 -XX:+PrintGCDetails
-XX:+PrintGCDateStamps -XX:+HeapDumpBeforeFullGC -XX:HeapDumpPath=/data/1/
-XX:+CMSDumpAtPromotionFailure -XX:+HeapDumpAfterFullGC
-XX:+PrintTenuringDistribution -XX:+PrintGCApplicationConcurrentTime
-XX:+PrintGCApplicationStoppedTime"
It used to run out of road -- full GC -- after 5 minutes or so.

> Trying to test branch-1, I run out of mem pretty fast. Looking at dumps, I
> see too many instances of LiteralByteString. Seem to be 'qualifiers' and
> 'values' out of pb QualifierValue... and on up to the multi call into the
> server. Am having trouble finding how the retention is being done... Filing
> issue in meantime while work on it.
