Job and partitioning configurations
Command Runner
To reproduce the issue, jobs should be launched with input parameters
batch_id=2014-06-08 and batch_id=2014-06-09
But if we launch these two jobs simuleteneously, data gets mixed, this is output I am getting
/home/[USER]/tmp/spring/batch/batch.log.2014-06-08
