--------------------------------------
Summary: QueryRecord hits a run time exception when using double
quotes
Key: NIFI-4047
URL: https://issues.apache.org/jira/browse/NIFI-4047
Project: Apache NiFi
Issue Type: Bug
Reporter: Joseph Percivall
To reproduce:
Attempt to run the below query. "first" is a reserved word so it needs to be
surrounded it in quotes.
SELECT "first" AS first_seen
FROM FLOWFILE
In doing so, the processor successfully validates and is ready to run. When
run, it hits the following RunTimeException:
16:16:31 EDT ERROR 82ec3eda-015c-1000-5f5e-3dbf6d4b3145
QueryRecord[id=82ec3eda-015c-1000-5f5e-3dbf6d4b3145] Unable to query
StandardFlowFileRecord[uuid=cd8d94cb-96b4-4daf-96a5-454d4d4640d9,claim=StandardContentClaim
[resourceClaim=StandardResourceClaim[id=1496946569360-1, container=default,
section=1], offset=6721, length=167],offset=0,name=22416107244401,size=167] due
to java.lang.RuntimeException: parse failed: Encountered "\"" at line 1, column
8.
Was expecting one of:
"UNION" ...
"INTERSECT" ...
(where it continues to list all the expected values)
I think the double quote is somehow getting mis-translated when being parsed by
the Calcite backend.
