Subject Spool files not deleted after client was killed
Date Mon, 13 Apr 2015 17:16:43 GMT
Hi All,

Our system uses phoenix-4.3.0 to give SQL-over-Hbase ability to end users. The system is not
implemented in Java, so for each query it just spawns a subprocess to execute Sqlline and
redirects its output to a file. To prevent large result file, the system will monitors size
of result file periodically, and kills the java process when the size exceeds some threshold.

The problem I found is that when the query is killed, phoenix will not delete the spool files
it uses. So over time, the spool files will fill the disk space.

Is it a bug? Any suggestion on how to deal with it? Thanks!
