             Summary: Avoid unnecessary ResultSpooler.bin files creation/deletion every time SpoolingResultIterator 
                 Key: PHOENIX-1396
                 URL: https://issues.apache.org/jira/browse/PHOENIX-1396
             Project: Phoenix
          Issue Type: Bug
            Reporter: Jeffrey Zhong


In SpoolingResultIterator.java, we have following code:

{code}
            tempFile = File.createTempFile("ResultSpooler",".bin", new File(spoolDirectory));
            DeferredFileOutputStream spoolTo = new DeferredFileOutputStream(size, tempFile) {
{code}
Basically we pre-create spill file even we don't cross memory threshold and later we delete in the same file if it's not needed in finally block. We can remove these unnecessary file creation & deletion altogether.
