Shanthoosh Venkataraman commented on SAMZA-1656:

Fix: Remove the redundant caching and initiate fetchMetadataRequest for each 
eventhub stream.

> EventHubSystemAdmin does not fetch metadata for valid streams.

>             Project: Samza
>          Issue Type: Bug
>            Reporter: Shanthoosh Venkataraman
>            Assignee: Shanthoosh Venkataraman
>            Priority: Major
> Currently successive invocation of 
> EventHubSystemAdmin.getSystemStreamMetadata with the same stream collection 
> returns empty results.
> This is an implementation bug, where the streams requested as a part of prior 
> invocations of EventHubSystemAdmin.getSystemStreamMetadata are ignored(due to 
> stale caching). 
> This bug causes the JobModel generation phase to fail and kills the 
> StreamProcessor.
