Daryn Sharp commented on HADOOP-10590:
--------------------------------------
Agreed on correct vs performance. Any update on performance though? My
concern relates to large clusters seeing bursts of thousands of connections per
second. I wouldn't expect much if any measurable impact, but stranger things
have happened. The test would need to stress 1 rpc connections to avoid
diluting the results.
