Apache Drill 1.4.0 Release Notes

+ +
+ + + + + +
+ +

Release date: December 14, 2015

+ +

Today, we're happy to announce the availability of Drill 1.4.0, providing the following bug fixes and improvements.

+ +

Drill 1.4 fixes an error that occurred when querying a Hive table using the HBaseStorageHandler (DRILL-3739). To successfully query a Hive table using the HBaseStorageHandler, you need to configure the Hive storage plugin as described in the Hive storage plugin documentation.
