> Hi,
> Sqoop cannot import and create Hive table when the table to be imported contains NCLOB
columns.
> Actually, data is correctly imported into HDFS but Hive table creation fails with :
> ERROR tool.ImportTool: Encountered IOException running import job: java.io.IOException:
Hive does not support the SQL type for column myNClobColumn

>         at org.apache.sqoop.Sqoop.main(Sqoop.java:244)
> That issue is due to the fact SQOOP knows CLOB type but not NCLOB. See type mappings
in org.apache.sqoop.hive.HiveTypes where NCLOB is not.
> Regards
