Change subject: IMPALA-14164: Fix timeout for fragments in flight in 
TestScratchDir
......................................................................


Patch Set 1: Code-Review+1

lgtm, but I think that waiting for num-fragments-in-flight is not the best way 
to handle these tests

http://gerrit.cloudera.org:8080/#/c/23081/1/tests/custom_cluster/test_scratch_disk.py
File tests/custom_cluster/test_scratch_disk.py:

http://gerrit.cloudera.org:8080/#/c/23081/1/tests/custom_cluster/test_scratch_disk.py@238
PS1, Line 238:     # There are two fragments, but one can finish so quickly 
that the metric is never
             :     # sampled as 2. Instead, wait for the metric to reach 1.
             :     
verifier.wait_for_metric("impala-server.num-fragments-in-flight", 1)
Wouldn't it be clearer + simpler to wait for the query to have rows available? 
At that point (unless result spooling consumes the whole data) the query must 
have spilled runs.
