via X-GP-FILTER
Key: HAWQ-1088
URL: https://issues.apache.org/jira/browse/HAWQ-1088
Project: Apache HAWQ
Issue Type: Sub-task
Components: PXF
Reporter: Shivram Mani
Assignee: Lei Chang
IF a query is provided with a constant containing quotes, it messes up with the
parsing logic on the java side.
Eg: select * from nametable where name = 's"hivram';
The filterstring being passed as X-GP-FILTER: a1c\"s"hivram\"o5
The Filter parser now interprest the constant and the operation incorrectly and
throws the below excpetion
{code}
ERROR: remote component error (500) from '127.0.0.1:51200': type Exception
report message unknown opcode h(104) at 6 (filter string:
'a1c"s"hivram"o5') description The server encountered an
internal error that prevented it from fulfilling this request. exception
