Sqoop Hcatalog export failed with exception of Failed to load foster storage handler during map reduce

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:
