Souvik Bose created SQOOP-1335:

             Summary: Sqoop Hcatalog export failed with exception of Failed to load foster
storage handler during map reduce
                 Key: SQOOP-1335
                 URL: https://issues.apache.org/jira/browse/SQOOP-1335
             Project: Sqoop
          Issue Type: Bug
          Components: hive-integration
    Affects Versions: 1.4.3
         Environment: CDH4.4.0 with cloudera manager.
            Reporter: Souvik Bose

I tried to export a hive external table to mysql using sqoop hcatalog export command.

sqoop export --connect jdbc:mysql://example.com:3306/demo1 --username demo-password demo1234
bd_sqoop1 --hcatalog-table test_data

I have set the HCAT_HOME, HADOOP_CLASSPATH, HIVE_HOME and paths of Jars. Now the job is progressing
upto the map reduce stage, but stops at map 0% reduce 0% with an exception as below:
