Subject [jira] [Created] (PHOENIX-1670) Investigate lease timeout on aggregate queries
Date Wed, 18 Feb 2015 03:22:11 GMT
James Taylor created PHOENIX-1670:

             Summary: Investigate lease timeout on aggregate queries
                 Key: PHOENIX-1670
             Project: Phoenix
          Issue Type: Bug
            Reporter: James Taylor

In theory, we shouldn't hit a lease timeout for aggregate queries, because we chunk up the
scan on the client side to manageable chunks. However, I believe [~mujtabachohan] has seen
this occurring. Another curious issue is that unless we open the scanner when the iterator
is created, aggregate scans take a perf hit which I don't completely understand. Another thing
that [~lhofhansl] noticed was that running the scan on the region server during the post scanner
open hook could be problematic. We might need to run the scan instead on the first next()
call we get from the client instead.
