notorious ClassNotFoundError
Guys,

The notorious error. Used all possible clues to resolve this.

Ran sqoop --import.... at command line without problems. But whenever am trying to execute MR job get Error: java.lang.ClassNotFoundException: com.cloudera.sqoop.lib.SqoopRecord

This exact same job ran before.

I can clearly see the com/cloudera/sqoop/lib/SqoopRecord.class inside  sqoop-1.4.1-cdh4.1.2.jar...

I copied this jar file to every possible directory:

/usr/lib/hadoop

/usr/lib/hadoop/lib

As well as mapreduce-0.20 libs

Even tried to include this jar at command line -libjars which is added to the job...

But MR still doesn't pick it up, throwing ClassNotFoundError error.

Rgds,

AK
