I have a web based appllication for  analytics over the data stored in Hbase .Every time User can query about any fix time duration data.But the response time to that query is about ~ 40 sec.On every request most of time is wasted in Context creation and Job submission .

1-How can i avoid context creation for every Job.
2-Can i have something like pool to serve requests .

Thanks & Regards,
