Hi, I'm trying to execute a simple hiveql statement like the following: insert into table1 select * from table2. Both tables have the same schema but different store options, that is, table1 is stored as avro and table2 as parquet. I copied jdbc4 driver to project's location and I can obtain a connection to hiveserver2 without any issues. However, when I try to execute the above query, the following exception occurrs. Only AEQuery is supported.
java.sql.SQLException: Only AEQuery is supported.

Caused by: com.cloudera.hive.support.exceptions.ErrorException: Only AEQuery is supported. Can somebody please tell me what I'm doing wrong or how this can be solved? This is my code: if (this.conn == null) {
this.conn = this.cm.connect();
}
Statement stmt = this.conn.createStatement();
String sql = "INSERT INTO " + toTable + " SELECT * FROM " + fromTable;
stmt.execute(sql);
stmt.close(); Thanks.
