Spark (1.2.0) submit fails with exception saying log directory already exists

[Varadhan, Jawahar]

Here is the error
yarn.ApplicationMaster: Final app status: FAILED, exitCode: 15, (reason: User 
class threw exception: Log directory 
hdfs://Sandbox/user/spark/applicationHistory/application_1438113296105_0302 
already exists!)
I am using cloudera 5.3.2 with Spark 1.2.0
Any help is appreciated.
ThanksJay
