I have written a script to perform an incremental import of data from oracle table to HDFS directory. I use the following sqoop command to do the import :

    sqoop -- import \
   --connect $JDBCconnectionString  \
   --username $dbUserName \
   --password-file $passwordLocal \
   --query 'select * from dmt_sim.dim_product WHERE $CONDITIONS' \
   --split-by "PRODUCT_TITLE" \
   --incremental append \
   --check-column "KEY" \
   --last-value "1" \
   --append \
   --fields-terminated-by '\t' \
   --target-dir /user/ksrinivasan/dmn_product

The values for the variables $JDBCconnectionString,$dbUserName, $passwordLocal is substituted during run so the connection to the oracle database and getting the boundary values all succeeds but when the job is started it throws an error.
