Summary: Fixed bug for maintaining compatibility of decimal type with older releases of Carbondata Key: CARBONDATA-1509 URL: https://issues.apache.org/jira/browse/CARBONDATA-1509 Project: CarbonData Issue Type: Bug Reporter: Manish Gupta Assignee: Manish Gupta Fix For: 1.2.0 In old Carbondata releases, precision and scale is not stored for decimal data type and both values are initialized to -1. In TableSpec.ColumnSpec default values for precision and scale are initialized to 0 because of which exception is thrown while reading the old store with decimal column.
