> Current instr() only supports two arguments:
> {code:java}
> instr(str, substr) - Returns the index of the first occurance of substr in str
> {code}
> Other systems (Vertica, Oracle, Impala etc) support additional position and
> occurrence arguments:
> {code:java}
> instr(str, substr[, pos[, occurrence]])
> {code}
> Oracle doc:
> [https://docs.oracle.com/database/121/SQLRF/functions089.htm#SQLRF00651]
> It'd be nice to support this as well. Otherwise, it's a SQL difference
> between Impala and Hive.
> Impala supports this in IMPALA-3973
