**Scenario:**
Data size: 3.5 billion rows(4.1 tb data)
3 node cluster
Number of core while data loading 12.
No. of loads 100 times
**Problem:** In DataConverterProcessorStepImpl it is using array list for
adding all the local converter, in case of multiple thread scenario it is
creating a hole (null value)(as array list if not synchronized). while closing
the converter it is it is throwing NPE
**Solution:** Add local converter in synchronized block
