> In WindowDataManager getLargestWindow during recovery is not reflecting the saved window
before operator crash.
> This affects many of the operators, one example is KafkaExactlyOnceOutputOperator, https://issues.apache.org/jira/browse/APEXMALHAR-2419
> Note: 
> WindowDataManager works as expected on a local machine(local filesystem), but not on
HDFS.
> Testing for the fix
> 1. Updated the unit test to use Hadoop filesystem APIs and ran them on HDFS
> 2. Wrote a simple application to test the behavior of Window Data Manager on the cluster
