Hi,
There are 500 concurrent clients request which trying to fetch data from
HBASE through our 10 application servers.
These requests will be equally dispatched to 10 application servers.
In my application server, I am using HBASE java API to fetch hbase data
by scan key and secindary index.
It took about 60 seconds if only one request.
Increasing to over 1000 seconds, while 500 concurrent request coming.
Requests in a application server are all sharing a HBASE configure and a
HTable instance for each table.
It seems no use after I increased my region server to 20.
Any suggestions?
Thank you very much
