Roman created DRILL-4963: ---------------------------- Summary: Issues when overloading Drill native functions with dynamic UDFs Key: DRILL-4963 URL: https://issues.apache.org/jira/browse/DRILL-4963 Project: Apache Drill Issue Type: Bug Components: Functions - Drill Affects Versions: 1.9.0 Reporter: Roman
I created jar file which overloads 3 DRILL native functions (LOG(VARCHAR-REQUIRED), CURRENT_DATE(VARCHAR-REQUIRED) and ABS(VARCHAR-REQUIRED,VARCHAR-REQUIRED)) and registered it as dynamic UDF. If I try to use my functions I will get errors: {code:xml} SELECT CURRENT_DATE('test') FROM (VALUES(1)); {code} Error: FUNCTION ERROR: CURRENT_DATE does not support operand types (CHAR) SQL Query null {code:xml} SELECT ABS('test','test') FROM (VALUES(1)); {code} Error: FUNCTION ERROR: ABS does not support operand types (CHAR,CHAR) SQL Query null {code:xml} SELECT LOG('test') FROM (VALUES(1)); {code} Error: SYSTEM ERROR: DrillRuntimeException: Failure while materializing expression in constant expression evaluator LOG('test'). Errors: Error in expression at index -1. Error: Missing function implementation: castTINYINT(VARCHAR-REQUIRED). Full expression: UNKNOWN EXPRESSION. But if I rerun all this queries after "DrillRuntimeException", they will run correctly. It seems that Drill have not updated the function signature before that error. Also if I add jar as usual UDF (copy jar to /drill_home/jars/3rdparty and restart drillbits), all queries will run correctly without errors. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
