Sqoop job fails with KiteSDK validation error for Oracle import

I am attempting to run a Sqoop job to load from an Oracle db and into Parquet format to a Hadoop cluster. The job is incremental.

Sqoop version is 1.4.6. Oracle version is 12c. Hadoop version is 2.6.0 (distro is Cloudera 5.5.1).

The Sqoop command is (this creates the job, and executes it):

$ sqoop job -fs hdfs://<HADOOPNAMENODE>:8020 \
--create myJob \
-- import \
--connect jdbc:oracle:thin:@<DBHOST>:<DBPORT>/<DBNAME> \
--username <USERNAME> \
-P \
--as-parquetfile \
--target-dir <HDFSPATH>  \
--incremental append  \
--check-column <TABLEPRIMARYKEY>

$ sqoop job --exec myJob

Error on execute:

Resolved. There seems to be a known issue with the JDBC connectivity to Oracle 12c. Using a specific OJDBC6 (instead of 7) did the trick. FYI - the OJDBC is installed in /usr/share/java/ and a symbolic link is created in /installpath.../lib/sqoop/lib/
