> Key: SAMZA-1607
> URL: https://issues.apache.org/jira/browse/SAMZA-1607
> Project: Samza
> Issue Type: Bug
> Reporter: Shanthoosh Venkataraman
> Assignee: Shanthoosh Venkataraman
> Priority: Major
>
> Existing implementation of reading the data of ephemeral processor nodes in zookeeper happens in two steps.
> A. Fetch the list of ephemeral processor nodes.
> B. Read the data of each processor node from the list.
>
> Some zookeeper nodes present in step A might be unavailable in the step B. This exception in unhandled currently and can kill the leader processor unnecessarily.
