Sqoop not able to map oracle column types to hive column
<p>I am sqooping a bunch of Oracle 10g tables in to hive. I am working on Hortonworks HDP2.3 on my cluster.
One of the oracle table with more than 100 columns has a ROW_ID column, which I found out is of type oracle.sql.ROWID.
Sqoop is throwing error :</p>

<p>Is there a way to map this oracle column type to any hive column type or just make it string?</p>
