to look at the new patch set (#2).

Change subject: IMPALA-11572: deflake test_mt_dop_skew_lpt

IMPALA-11572: deflake test_mt_dop_skew_lpt

test_mt_dop_skew_lpt was flaky. Also, it calculated the
min(bytes_read) / max(bytes_read) globally across all fragment
insteances, not just among the intra-node fragment instances.

To deflake the test, this test:
 * calculate intra-node min(bytes_read) / max(bytes_read) ratios
   instead of global ones
 * print out the ratios so we'll know the numbers when the test fails
 * eliminate compression codec test dimension which is not used anyway
