Subject Re: Too many delete delay

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

     Is this the reason delete delay too much? And how can I repair this without shutdown

Have you checked region server logs to see if there was some clue ?

If so, mind pastebin'ing some snippet ?

Most of them are Delete! I found the table has too many storefiels, so i do a major_compact,
then things be better. After an hour, timeout again! I don't know why so many delay in delete,
not put, not scan. Can anyone tell me, when will delete operation  use too much time? Thanks!
