sqoop server start failed

Question

I am trying to connect to a sqoop server on localhost:

sqoop:000> set server --host manager --port 12000 --webapp sqoop
Server is set successfully
sqoop:000> show version -all
client version:
  Sqoop 1.99.6 source revision 07244c3915975f26f03d9e1edf09ab7d06619bb8 
  Compiled by root on Wed Apr 29 10:40:43 CST 2015
0    [main] WARN  org.apache.hadoop.util.NativeCodeLoader  - Unable to load native-hadoop library for your platform... using builtin-java classes where applicable
Exception has occurred during processing command 
Exception: org.apache.sqoop.common.SqoopException Message: CLIENT_0000:An unknown error has occurred
sqoop:000> 


Port 12000 is closed

    $ netstat -na|grep 12000 

Why is this happening?

Answer 1

Hadoop libraries need to be set in a file named catalina.properties inside directory server/conf. In this file, you need to set the hadoop libraries path in common-loader property. Default will be /usr/lib/hadoop and /usr/lib/hadoop/lib. If you have your hadoop libraries at any different locations then point that directory in this property.

sqoop2-tool verify can be used to verify all the sqoop server configurations. If it is successful, you can start your server using sqoop2-server start.
