Wenzhe Zhou has uploaded a new patch set (#3). ( http://gerrit.cloudera.org:8080/21218 )
Change subject: IMPALA-12925: Fix decimal data type for external JDBC table ...................................................................... IMPALA-12925: Fix decimal data type for external JDBC table Decimal type is a primitive data type for Impala. Current code returns wrong values for columns with decimal data type in external JDBC tables. This patch fixes wrong values returned from JDBC data source, and supports pushing down decimal type of predicates to remote database and remote Impala. Testing: - Added Planner test for pushing down decimal type of predicates. - Added end-to-end unit-tests for decimal data type. - Passed core-tests.
