Daniel Barclay (Drill) updated DRILL-3954:
------------------------------------------
Description:
Currently, the HBase tests (e.g., {{TestHBaseFilterPushDown}}) use only one
region.
That causes them to miss detecting a bug in creating and/or resolving dummy
fields ({{NullableIntVectors}} for referenced but non-existent fields)
somewhere between reading from HBase and wherever dummy fields are supposed to
be get resolved (or maybe two separate bugs).
Reproduction:
In HBaseTestsSuite, change the line:
{noformat}
UTIL.startMiniHBaseCluster(1, 1);
{noformat}
to:
{noformat}
UTIL.startMiniHBaseCluster(1, 3);
{noformat}
and change the line:
{noformat}
TestTableGenerator.generateHBaseDataset1(admin, TEST_TABLE_1, 1);
{noformat}
to:
{noformat}
TestTableGenerator.generateHBaseDataset1(admin, TEST_TABLE_1, 3);
{noformat}
.
Run unit test class {{TestHBaseFilterPushDown}}.
Depending on which region gets processed first (it's non-deteministic), test
methods {{testFilterPushDownOrRowKeyEqualRangePred}} and
{{testFilterPushDownMultiColumns}} get exceptions like this:
{noformat}
