> While fixing HIVE-22140 I found some really annoying differences between the codahale
metric file structures between hiveserver2 and metastore, e.g.
> open_connections: can be found in "counters" for hs2, but in "gauges" for ms
> threads count: it's a proper "threads.count" for hs2, but a really ambiguous "count"
for ms
> so I realized that "memory." and "threads." prefix is completely absent in ms metrics
file, which is misleading
