Ich weiß, dass Apache Phoenix alle Funktionsmetadaten in SYSTEM.FUNCTION speichern wird, aber wenn ich die Abfrage benutze, folge der folgenden Anweisung, die Ausnahme auszulösen.Phoenix sqline kann Systemtabelle nicht abfragen SYSTEM.FUNCTION
0: jdbc:phoenix:10.1.226.15:2181> select * from SYSTEM.FUNCTION;
Error: ERROR 604 (42P00): Syntax error. Mismatched input. Expecting "NAME", got "FUNCTION" at line 1, column 22. (state=42P00,code=604)
org.apache.phoenix.exception.PhoenixParserException: ERROR 604 (42P00): Syntax error. Mismatched input. Expecting "NAME", got "FUNCTION" at line 1, column 22.

oder
0: jdbc:phoenix:10.1.226.15:2181> select * from FUNCTION;
Error: ERROR 601 (42P00): Syntax error. Encountered "FUNCTION" at line 1, column 15. (state=42P00,code=601)
org.apache.phoenix.exception.PhoenixParserException: ERROR 601 (42P00): Syntax error. Encountered "FUNCTION" at line 1, column 15.
Die Tabelle FUNCTION existieren in SYSTEM-Schema, kann aber nicht abfragen, in anderer Seite der Tabelle Katalog in SYSTEM Schema I Anweisung und ruft die richtigen Daten durchführen kann.
