impala jdbc not support UPSERT preparestatement (KUDU)

impala jdbc not support UPSERT preparestatement (KUDU)

JDBC version is impala_jdbc_2.5.37.1057

code is like below:

conn.setAutoCommit(false);
PreparedStatement pstmt = conn.prepareStatement(sqlStatement);
for (ArrayList<String> ss : list) {
    for (int i=0;i<types.length;i++) {
        String s = "NULL";
        if (i < ss.size()) s = ss.get(i);
        setDataValue(i+1, pstmt, types[i], s);
    }
    pstmt.addBatch();
}
pstmt.executeBatch();
pstmt.close();
conn.setAutoCommit(true);


when the sqlStatement is using INSERT it's ok, but when using UPSERT, it report below exceptions

Exception in thread "main" java.sql.SQLException: [Simba][ImpalaJDBCDriver](500057) Multi-batch parameter values not supported for this query type.

Re: impala jdbc not support UPSERT preparestatement (KUDU)

Hi,

 

Two questions:

 

1) What query are you trying to execute?

 

2) Can you try adding the "UseNativeQuery=1" option to the jdbc driver connection string? (see http://www.cloudera.com/documentation/other/connectors/impala-jdbc/latest/Cloudera-JDBC-Driver-for-I... for details)

 

Thanks

Re: impala jdbc not support UPSERT preparestatement (KUDU)

we try "UseNativeQuery=1" option to the jdbc driver connection string, the result is same as before.
