I started a apache phoenix query server, phonenix version is apache-phoenix-5.0.0-HBase-2.0-bin All other functions work well in the cmd line of sqlline-thin.py. But when I tried to get the primary key of a table, its just listed nothing.  0: jdbc:phoenix:thin:url=http://localhost:876> !primarykeys FN2.TESTYL2 +------------+--------------+-------------+--------------+----------+----------+ | TABLE_CAT | TABLE_SCHEM | TABLE_NAME | COLUMN_NAME | KEY_SEQ | PK_NAME | +------------+--------------+-------------+--------------+----------+----------+ +------------+--------------+-------------+--------------+----------+----------+   when I tried in phoenix cmd line sqlline.py, it works well. do you know why the thin phoenix query server cannot find the primary key?   thanks Yang ...
