> WindowDataManager not recovering as expected on HDFS
> ----------------------------------------------------
>
> Key: APEXMALHAR-2422
> URL: https://issues.apache.org/jira/browse/APEXMALHAR-2422
> Project: Apache Apex Malhar
> Issue Type: Bug
> Affects Versions: 3.5.0, 3.6.0, 3.7.0
> Reporter: Sandesh
> Assignee: Sandesh
>
> 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
