We ran into something similar, here is the ticket https://issues.apache.org/jira/browse/PHOENIX-2685 The work around that mitigated this issue for us was to lower the value of phoenix.query.spoolThresholdBytes to 10 MB. It is counter intuitive, but, due to the way the spooling iterator interacts with global memory manager, it works.
