Yes, there's a Thrift RPC -- the easiest way to call it is to use the shell
as follows: impala-shell -q "refresh"
IMPALA-387 <
https://issues.cloudera.org/browse/IMPALA-387> aims to make
refresh a first-class statement in our SQL dialect, and should make
refreshing the catalog through JDBC and ODBC much easier.
I've filed IMPALA-426 <
https://issues.cloudera.org/browse/IMPALA-426> to
track Avro table creation support. While I doubt this will make it into the
next release, we'll try to resolve this as soon as possible.
Thanks,
Skye

If I create an avro table in Hive, Impala can read it without problem, but
I cannot run the same create table statement in Impala because Impala
doesn't support SerDe row format and INPUT FORMAT and OUTPUT FORMAT for
"stored as".
My problem is: If I can run a create-table query through JDBC driver, I
don't have to "refresh" Impala. Otherwise, I need to refresh Impala to read
the avro tables created by Hive. Unfortunately JDBC driver doesn't support
refresh query now.
Is there a thrift call for "refresh"?
When will impala support creating avro table?
