Subject IMPALA-4624 requires reload of data for local PlannerTest runs
Date Tue, 07 Mar 2017 00:09:59 GMT
IMPALA-4624 changes Impala's Parquet writer to fill in the column chunk
metadata's encoding_stats field. This changed the file size for some of the
Parquet files used in our tests, resulting in a diff in
PlannerTest::testPredicatePropagation. Since the log file is now updated to
the new file sizes, any run of PlannerTest with the old tables will hit
this diff. The two tables involved are tpch_parquet.regionkey and
tpch_parquet.nation. Here is a workaround short of a full data reload:

use tpch_parquet;
insert overwrite table nation select * from nation;
insert overwrite table region select * from region;

It is possible that other tests that are not run as part of the normal test
suite may have a similar issue.

Thanks,
Joe
