             Summary: Surround the OR filter with parentheses while converting spark filters to phoenix expessions
                 Key: PHOENIX-6683
                 URL: https://issues.apache.org/jira/browse/PHOENIX-6683
             Project: Phoenix
          Issue Type: Bug
          Components: spark-connector
            Reporter: Rajeshbabu Chintaguntla
            Assignee: Rajeshbabu Chintaguntla


If there are mix of *AND* and *OR* filters in the query while converting the to phoenix filter from spark filters no parentheses got added to *OR* filters  which is leading to wrong filter and finally getting wrong data.

For example if the filter is used is below
{code}
 where ENTITY_INSTANCE_ID = 40 and  (CANCELLATION_FLAG <> 'Y' OR CANCELLATION_FLAG IS NULL ) and CASE_MATCH_TYPE='M'
{code}

which is getting converted to an expression and leading to wrong result because result is always giving most of the records matching CANCELLATION_FLAG is not 'Y'
{code}
NOT  "CANCELLATION_FLAG" = 'Y' OR  "CANCELLATION_FLAG" IS NULL AND "CASE_MATCH_TYPE" IS NOT NULL AND "ENTITY_INSTANCE_ID" = 40 AND "ENTITY_INSTANCE_ID" IS NOT NULL AND "CASE_MATCH_TYPE" = 'M'
{code}
