Fixes
Drill 1.12.0-1808 provides the following fixes:
| Fix Tracking Numbers | Descriptions |
|---|---|
| MD-4509 | Query plans with CAST indexes are generated for LIKE filters with CAST functions. |
| MD-4444 | Issuing the CTAS command against a MapR Database table no longer returns a NullPointerException. |
| MD-4156 | Queries on a single Parquet column no longer fail with an ArrayIndexOutOfBoundsException. |
| MD-4048 | The io.dropwizard.metrics have been removed from Drill. |
| MD-3979 | Queries that use CAST index plans no longer fail with a NullPointerException. |
| MD-3716 | (DRILL-6223) Queries on complex nested data in Parquet files no longer fail when selecting on all columns. |
| MD-3544 | Queries on complex nested data in Parquet files no longer fail. |
| DRILL-6557 | Drill no longer fetches all the input splits when Hive statistics provide the number of bytes, which improves query planning time for queries on Hive data. |
| DRILL-6204 | When the store.hive.optimize_scan_with_native_readers option is enabled, Drill separates the partitioned columns from the non-partition columns when reading Hive data directly from the filesystem. This prevents Drill from returning an error if the reader cannot find partitioned columns in the table schema. |
| DRILL-6195 | Drill can query Hive partitioned bucketed tables. |
| DRILL-6164 | Drill no longer returns out-of-memory errors due to memory leaks caused by the buildup of Parquet reader references that the scanner does not remove. |
| DRILL-5978 | Hive libraries are updated to version 2.1.2-mapr-1710. |
| DRILL-4185 | Drill supports queries with JOIN and UNION [ALL] operators on empty directories. |
