Description

When I'm importing a table from Oracle which takes more than 1 hour to extract, I'm getting following error message at the stage when Sqoop tries to import data from temporary HDFS location to Hive:

14/05/27 13:05:51 INFO mapreduce.ImportJobBase: Transferred 47.2606 GB in 6,389.4644 seconds (6.7206 MB/sec)

With small tables (under 1 hour) everything is fine.

I'm using Sqoop v1.4.4

14/05/27 13:49:14 INFO sqoop.Sqoop: Running Sqoop version: 1.4.4-cdh5.0.0

This problems looks exactly as described in (SQOOP-934) issue.
