--------------------------------------
[~tarmstrong], assigning to you, since you made the last change here.
I've pushed a review for @SkipIf workaround:
https://gerrit.cloudera.org/c/16964/ . Since it takes about 5 hours for GVO to
complete, feel free to approve this patch for a quick workaround, or suggest a
better fix; the timeline will be more or less the same either way.

> The test fails for all debug actions exercised in the test set.
> Error backtrace is:
> {code}
> query_test/test_scanners.py:1006: in test_bytes_read_per_column
> assert len(compressed_bytes_read_per_col_summaries) == 4
> E assert 2 == 4
> E + where 2 = len([TSummaryStatsCounter(total_num_values=0, name=None,
> max_value=0, sum=0, min_value=0, unit=None),
> TSummaryStatsCounter(total_num_values=0, name=None, max_value=0, sum=0,
> min_value=0, unit=None)])
> {code}
> The symptom on builds testing HDFS erasure-coding is slightly different (the
> mismatching number is different):
