Maybe I am missing something, though I followed your suggestion and decreased
the "phoenix.query.spoolThresholdBytes" value to 10MB, though after some time I
am still running out of disk space (350+GB). Any suggestions?

We ran into something similar, here is the ticket
https://issues.apache.org/jira/browse/PHOENIX-2685The 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.

What version of phoenix are you using? Is the application properly closing
statements and result sets?

I am running into an issue where a huge number temporary files are being

big and never get cleaned up. These *.tmp files grew to around 200GB before I
stopped the server.
Example file names:

Currently, I have my Phoenix Client jar deployed to Wildfly 10 as described
here: https://docs.jboss.org/author/display/TEIID/Phoenix+Data+Sources
These *.tmp files only appear when I run SELECT queries.
Any help would be appreciated.
