I am trying to connect to impala using JDBC connection. Imapala driver jar used is impalaJDBC41. Error occured while creating connection object 'con' Error is -[Simba]ImpalaJDBCDriver Error setting/closing session in Imapala jdbc connection

    public static void main(String[] args) throws SQLException {
    try {
       Class.forName(driverName);

        } 
   catch (ClassNotFoundException e)
       {
            // TODO Auto-generated catch block

            System.exit(1);
        }
         Connection con =   DriverManager.getConnection("jdbc:impala://host:25004/;principal=impala/[email protected]");

url should be: jdbc:impala://192.168.8.183:21050;AuthMech=1;KrbRealm=abc.ENTERPRISENET.ORG;KrbHostFQDN=your-host;KrbServiceName=impala

and kerberos need hadoop kerberos env

System.setProperty("sun.security.krb5.debug", "false");
System.setProperty("java.security.krb5.conf",loader.getResource("secret/krb5.ini").getPath());
org.apache.hadoop.conf.Configuration conf = new org.apache.hadoop.conf.Configuration();
conf.set("hadoop.security.authentication", "Kerberos");
UserGroupInformation.setConfiguration(conf);
UserGroupInformation.loginUserFromKeytab("hdfs/[email protected]", loader.getResource("secret/184_hdfs.keytab").getPath());
        UserGroupInformation loginUser = UserGroupInformation.getLoginUser();
        loginUser.doAs(new PrivilegedAction<Void>() {
            @Override
            public Void run() {
                connectImpala();
                return null;
            }
        });
}

I had the same error (code 500151) with the Cloudera JDBC driver for Hive, and was able to solve it by adding ;SocketTimeout=0 to my connection string.
