             Summary: Support decimal data type for external JDBC table
                 Key: IMPALA-12925
                 URL: https://issues.apache.org/jira/browse/IMPALA-12925
             Project: IMPALA
          Issue Type: Sub-task
          Components: Frontend
            Reporter: Wenzhe Zhou


The data types in unit-test table alltypes do not include decimal. The decimal 
data type is not handled in DataSourceScanNode.java 
(https://github.com/apache/impala/blob/master/fe/src/main/java/org/apache/impala/planner/DataSourceScanNode.java#L152),
 but decimal type is listed as supported primitive data type in 
DataSourceTable.java. 
(https://github.com/apache/impala/blob/master/fe/src/main/java/org/apache/impala/catalog/DataSourceTable.java#L153)
