Thanks, Ted.
I see thousands upon thousands 'periodicFlusher requesting flush for
region' logs. I guess the conf 'hbase.regionserver.optionalcacheflushinterval'
effects this! We use the default 1h.
Is this the reason delete delay too much? And how can I repair this
without shutdown cluster?

Have you checked region server logs to see if there was some clue ?
If so, mind pastebin'ing some snippet ?
Cheers
