Davide Grohmann commented on SQOOP-477:
---------------------------------------
Hi Jarek,
well my use case is about importing several tables into Hadoop in different
threads, in order to distribute the work as much as possible.
Doing this causes a race condition in the OptionBuilder because it is not
thread safe.
