With the support for HCatalog added to Sqoop, any HCatalog job depends on a set of jar files being available both on the Sqoop client host and where the Map/Reduce tasks run. To run HCatalog jobs, the environment variable HADOOP_CLASSPATH must be set up as shown below before launching the Sqoop HCatalog jobs:

HADOOP_CLASSPATH=$(hcat -classpath) 
export HADOOP_CLASSPATH

The necessary HCatalog dependencies will be copied to the distributed cache automatically by the Sqoop job.
