> Our current [import rutine|https://github.com/apache/sqoop/blob/trunk/src/java/org/apache/sqoop/tool/ImportTool.java#L385]
imports data into HDFS and then tries to do Hive import. As the connection to the remote server
is opened only once at the begging it might timeout during very long mapreduce job. I believe
that we should ensure that the connection is still valid before performing the hive import.
