----------------------------------

             Summary: Escape string constants in filters being passed to PXF 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   java.io.IOException: unknown opcode h(104) at 6 (filter string: 'a1c"s"hivram"o5') (libchurl.c:884)  (seg5 localhost:40000 pid=28874)
DETAIL:  External table hive_smallorc
