We get stuck during the loading phase and t= he loader job eventually fails.=20 > All testing is done in an insecure environment under the same UNIX user (= clusterdock) so effectively all ops are issued by the superuser. > Doing unrelated work - or so I thought! - I was looking at object allocat= ions by YCSB workload by thread and when looking at the RegionServer RPC th= reads noticed that for 0.98.22 and 1.1.6, as expected, the vast majority of= allocations are from threads named "B.defaultRpcServer.handler*". In 1.2.0= and up, instead the vast majority are from threads named "PriorityRpcServe= r.handler*" with very little from threads named "B.defaultRpcServer.handler= *". A git bisect to find the change that causes this leads to HBASE-13375,= and so of course this makes sense out of what I am seeing, but is this rea= lly what we want? What about production environments (insecure and degenera= te secure) where all ops are effectively issued by the superuser? We run on= e of these at Salesforce. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
