Hi,

I've tried using phoenix-4.6.0-Hbase-1.1 and  phoenix-4.7.0-Hbase-1.1 to test if UNNEST is now available but it returns a syntax error.

Both are resulting to this error

sqlline version 1.1.8
0: jdbc:phoenix:localhost> SELECT t.k FROM UNNEST((SELECT k FROM a)) AS t(k);
Error: ERROR 601 (42P00): Syntax error. Encountered "(" at line 1, column 24. (state=42P00,code=601)

Even this simple one is resulting to syntax error:

Am I missing something? Or UNNEST is really not available yet on phoenix-4.7.0-Hbase-1.1 and phoenix-4.6.0-Hbase-1.1.
BTW, I used this file as reference for the query syntax: https://github.com/apache/phoenix/blob/4.7.0-HBase-1.1/phoenix-core/src/it/java/org/apache/phoenix/end2end/UnnestArrayIT.java 

Also, I have verified that I'm running phoenix-4.7.0-Hbase-1.1 and phoenix-4.6.0-Hbase-1.1.


Thanks!
