We see the failure is because of the following cause:  

ERROR tool.ImportTool: Import failed: org.apache.hadoop.mapred.FileAlreadyExistsException: Output directory hdfs://gaian-lap386.com:8020/user/gaian/emp already exists

You already have the output directory in HDFS "hdfs://gaian-lap386.com:8020/user/gaian/emp" existing hence it is failing.

You can easily check it as

# su - hdfs -c "hdfs dfs -ls /user/gaian/emp"

So either specify a different table / target dir OR specify the following property in your SQOOP command.

"--delete-target-dir Delete the import target directory if it exists"

Please refer to the mentioned doc to know what it actually does and if it is feasible for you or not?

OR you can try defining a different "--target-dir" (to define another HDFS destination dir) in the command line.
