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

             Summary: Query hint ignored for functional index
                 Key: PHOENIX-2094
                 URL: https://issues.apache.org/jira/browse/PHOENIX-2094
             Project: Phoenix
          Issue Type: Bug
            Reporter: Bryan Gerber


Hints are not being used for functional index.
 
EXPLAIN SELECT /*+ INDEX(LOG LOG_LOWER_REQUEST_IDX) */ * FROM LOG WHERE LOWER(RQ) LIKE '/jquery%';
+------------------------------------------+
| CLIENT 40-CHUNK PARALLEL 40-WAY FULL SCAN OVER LOG |
|     SERVER FILTER BY LOWER(RQ) LIKE '/jquery%' |
+------------------------------------------+
 
Test table has 2.9 million records; production table is many orders of magnitude larger. 
Here’s a simplified schema for the test table:
CREATE TABLE IF NOT EXISTS LOG
(
    TS VARCHAR NOT NULL,
    f VARCHAR NOT NULL,
    r INTEGER NOT NULL,
    sa VARCHAR,
    da VARCHAR,
    rq VARCHAR
CONSTRAINT pkey PRIMARY KEY (TS, f, r)
) TTL='5616000',KEEP_DELETED_CELLS='false',IMMUTABLE_ROWS=true,COMPRESSION='SNAPPY',SALT_BUCKETS=40,MAX_FILESIZE='10000000000',SPLIT_POLICY='org.apache.hadoop.hbase.regionserver.ConstantSizeRegionSplitPolicy';
 
CREATE INDEX IF NOT EXISTS LOG_LOWER_REQUEST_IDX  ON LOG(LOWER(rq)) TTL='5616000',KEEP_DELETED_CELLS='false',COMPRESSION='SNAPPY',MAX_FILESIZE='10000000000',SPLIT_POLICY='org.apache.hadoop.hbase.regionserver.ConstantSizeRegionSplitPolicy';
CREATE INDEX IF NOT EXISTS LOG_REQUEST_IDX  ON LOG(rq) TTL='5616000',KEEP_DELETED_CELLS='false',COMPRESSION='SNAPPY',MAX_FILESIZE='10000000000',SPLIT_POLICY='org.apache.hadoop.hbase.regionserver.ConstantSizeRegionSplitPolicy';
