We are not able to connect to Netezza from EMR via sqoop connection. Below is the error message. I am wondering if there is some port need to be open in Netezza host. Thanks.

I have imported data from mysql to hdfs successfully with avro file. But when I export data back
sqoop export --connect jdbc:mysql://localhost:3306/sakila --username root --password P#ssword --table actor --export-dir /hdfs/mysql/actor
I got the error

How can I fix it ? (I use sqoop 1.4.7 and hadoop 2..9.0, jdk 1.8.0)
Many thanks

your jdbc is not exist in sqoop/lib so download your valid jdbc driver and copy to sqoop/lib
