Question

I am trying to load data from MySQL to HDFS by using below query:

$ sqoop import --connect jdbc:mysql://127.0.0.1:3306/userdb \
--username root --password pwd \
--driver com.mysql.jdbc.Driver --table import-all-tables \
--m 1 --target-dir /user/cloudera/foldername

I get a "communications link failure error".

1. MYSQL Source: Installed in my local computer
2. HDFS Destination: Cloudera in virtual machine

Please help me how to load data from my local computer to cloudera HDFS .
