Tim Armstrong has uploaded a new patch set (#2). Change subject: IMPALA-3670: fix sorter buffer mgmt bugs ......................................................................
IMPALA-3670: fix sorter buffer mgmt bugs Also make test_scratch_disk.py more deterministic, by using max_block_mgr_memory, which doesn't include scanner memory. The fixed test_scratch_disk.py exercises the other sorter bugs that occurs when scratch cannot be written. Testing: Added a test that does a sort with various memory limits and consumes the whole output of the sorter (we have many tests of sorts with limits but limited coverage of sorts without limits). Ran an exhaustive test run before posting for review. This added test reproduced one of the sorter bugs, where var-len blocks were not always attached to the output batch. The other test was reproduced by the test change in IMPALA-3669: test_scratch_disk fix.
