Hi ,
   To improve client performance I  changed
hbase.client.scanner.caching from 1 to 50.
After running client with new value( hbase.client.scanner.caching from = 50
) it didn't improve execution time at all.

I have ~ 9 million small records.
I have to do full scan  , so it brings all 9 million records to client .
My assumption -- this change have to bring significant improvement , but it
is not.

Additional Information.
I scan table which has 100 regions
5 server
20 map
4  concurrent map
Scan process takes 5.5 - 6 hours. As for me it is too much time? Am I write?
and how can I improve it


I changed the value in all hbase-site.xml files and restart hbase.

Any suggestions.
