Never ending imports from Netezza

Hi,
there are situations where a Netezza import may fail but never end (i.e. the map reduce job will run for ever).

That occurs when Sqoop manages to open a connection to the database and executes a query that fails on the Netezza side without writing anything into the connection. For instance, that typically occurs for authroization problems.
Then you have to kill the map reuce job by hand if you want to free the resource (memory) kept by the MR container.
