----------------------------------
Summary: Resolve regressions to MapR DB from DRILL-5546
Key: DRILL-5830
URL: https://issues.apache.org/jira/browse/DRILL-5830
Project: Apache Drill
Issue Type: Bug
Affects Versions: 1.12.0
Reporter: Paul Rogers
Assignee: Paul Rogers
Fix For: 1.12.0
DRILL-5546 added a number of fixes for empty batches. One part of the fix was
for HBase. Key changes:
* Add code to expand wildcards in the planner. (i.e. SELECT *)
* Remove support for wildcards in the HBase record reader.
As noted in DRILL-5775, this change had the effect of breaking support for
MapR-DB binary (which is API compatible with HBase.) DRILL-5775 does this by
expanding wildcards in the planner for MapR DB as was done for HBase in
DRILL-5546.
Unfortunately, this change introduced other regressions into the code as
described by DRILL-5706.
Investigation of those issues revealed that we should back out the original
DRILL-5546 changes and go down a different route.
