>          Issue Type: Bug
>    Affects Versions: 4.0.0
>         Environment: HBase 0.96.1.1+cdh5.0.1+68

> The following SQL will execute correctly and produce an execution plan:
> ====
> DROP TABLE IF EXISTS I;
> DROP TABLE IF EXISTS P;
> CREATE TABLE I (
>   ID BIGINT NOT NULL, 
>   ID2 BIGINT NOT NULL,
>   CONSTRAINT FB_PK PRIMARY KEY (ID, ID2)
> );
> CREATE TABLE P (
>   ID BIGINT NOT NULL,  
>   PG.C2 VARCHAR(100), 
>   PG.C3 VARCHAR(100)
>   CONSTRAINT FB_PK PRIMARY KEY (ID)
> );
> EXPLAIN SELECT I.ID2 
> FROM P INNER JOIN I ON P.ID = I.ID 
> WHERE P.C3 = 'X';
> ====
> Now add an index & re-run the execution plan:
> ====
> CREATE INDEX P_IDX1 ON P (PG.C2);
> EXPLAIN SELECT I.ID2 
> FROM P INNER JOIN I ON P.ID = I.ID 
> WHERE P.C3 = 'X';
> ====
> You will get the error:
> Error: ERROR 504 (42703): Undefined column. columnName=P.C3 (state=42703,code=504
> ====
> Adding an index that INCLUDEs that missing column works around the issue:
> ====
> CREATE INDEX P_IDX2 ON P (PG.C2) INCLUDE (PG.C3);
> EXPLAIN SELECT I.ID2 
> FROM P INNER JOIN I ON P.ID = I.ID 
> WHERE P.C3 = 'X';
> ====
> This fault is related also to the compound key in table I.
> Having a workaround with an anti-index hint would be helpful
