Hi there,
HBase read performance works fine in most of the time,
but it took a very long time (over 500 seconds) yesterday while scan a few
records(it takes 2 seconds while HBase is normal)
I don't know how to do at that time; it lasted about 1 hour long, HBase
return to normal status.
So, my question is that any log or tool I can use it to know what's wrong
with HBase at that time.
I am afraid that compaction would do that great impact on read/write
performance. If so, any tunning I can do.
thank you.
