* #62 - Adding an optional -f flag to hadoop copy commands in case of hadoop2 clusters.
* #67 - Added retries while updating the job to status running after successful launch.
* Changed scripts to create a sample cluster with version 2.4.0.
Not really. The job is already entered in the DB and launched by the genie node. So retries would probably fix any transient query issues. Even if wanted to limit the retry to a particular scenario, i could not find any exception that informed that a deadlock was the cause. It was in the message though, but i did not want to rely on the message.
