Billy Pearson commented on HBASE-1185:
--------------------------------------
I get my second number from a MR Job so yes number of records by the total job
runtime
what I was saying about the 2 secs before in the past we reported
request in the gui on a 3 sec interval now we take the count and report it per
sec. pre 0.19.0 I thank
0.18.0 maybe before that its been a while.
I thank the problem I am seeing is coming from the hbase.client.scanner.caching
if it is set to 20 is that counted as 1 request or as 20 when we are scanning?
> wrong request/sec in the gui reporting wrong

> Key: HBASE-1185
> URL: https://issues.apache.org/jira/browse/HBASE-1185
> Project: Hadoop HBase
> Issue Type: Bug
> Components: client, regionserver
> Affects Versions: 0.19.0
> Environment: 0.19.0
> Reporter: Billy Pearson
> Priority: Minor
> Fix For: 0.20.0
>
>
> I am seeing lower number of request in the masters gui then I have seen in
> 0.18.0 while scanning.
> I thank part of it is we moved to report per sec request not per 3 secs so
> the request should be 1/3 of the old numbers I was getting.
> hbase.client.scanner.caching is not the reason the request are under reported.
> I set hbase.client.scanner.caching = 1 and still get about 2K request a sec
> in the gui
> but when the job is done I take records / job time and get 36,324/ records
> /sec. So
> there must be some caching out side of the hbase.client.scanner.caching
> making the
> request per sec lower then it should be. I know it running faster then
> reported just thought
> it might give some new users the wrong impression that request/sec =
> read/write /sec.
