Matt Burgess updated NIFI-5095: ------------------------------- Resolution: Fixed Status: Resolved (was: Patch Available) > PutHiveQL should not log warning message when it fails to parse SET property > command > ------------------------------------------------------------------------------------ > > Key: NIFI-5095 > URL: https://issues.apache.org/jira/browse/NIFI-5095 > Project: Apache NiFi > Issue Type: Bug > Components: Extensions > Affects Versions: 1.5.0 > Reporter: Koji Kawamura > Assignee: Koji Kawamura > Priority: Minor > Fix For: 1.7.0 > > > PutHiveQL can accept multiple queries separated by a specified delimiter > string, ';' by default. It supports users to specify Hive parameters by 'SET' > statement. E.g. set 'hive.exec.dynamic.partition.mode'=nonstrict > PutHiveQL also parses each query string with Hive ParseDriver, in order to > find input/output table names within queries. However, the aforementioned > 'SET' command is not a valid Hive query. The only query can start with 'SET' > is 'SET ROLE'. > [https://raw.githubusercontent.com/apache/hive/master/ql/src/java/org/apache/hadoop/hive/ql/parse/HiveParser.g] > When set property statement is parsed, following warning message is logged > and shown in the NiFi UI: > {code:java} > 2018-04-19 05:34:05,616 WARN [Timer-Driven Process Thread-8] > o.apache.nifi.processors.hive.PutHiveQL > PutHiveQL[id=db408703-0162-1000-0000-000073ad3455] Failed to parse hiveQL: > set hive.exec.dynamic.partition.mode=nonstrict due to > org.apache.hadoop.hive.ql.parse.ParseException: line 1:4 missing KW_ROLE at > 'hive' near 'hive' line 1:8 missing EOF at '.' near 'hive': > {code} > In case there are other DML statements such as 'INSERT ...' in the same > FlowFile content, those queries are performed successfully regardless of > having above parse failure.
