Im going to get data from RDMS to HDFS using Sqoop. i got the commands that i need to do this, But after putting those commands on Putty. It doesn't recognize at all. Is there anything that i need to do first before i can put some command of sqoop on putty ? or is there another command shell for hadoop?
From your screenshot we see that sqoop client is installed on 3 Hosts in your HDP cluster. So when you click on the "Sqoop Client" link then you should be able to find the 3 hosts (table) that has the sqoop client installed.
Please check if the host where you are trying to run the sqoop is included in the list or not?
It is better to place only one jar of the same type in the lib.. else if there is a bug assicoated with any particular version of the JAR then it will require further debugging to know the buggy class was loaded from jar1 or jar2. So i will suggest you to remove one duplicate jar from the lib.
