[jira] [Commented] (SAMZA-1656) EventHubSystemAdmin does not fetch metadata for valid streams.

    [ https://issues.apache.org/jira/browse/SAMZA-1656?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16437943#comment-16437943 ] 

Shanthoosh Venkataraman commented on SAMZA-1656:
------------------------------------------------

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

> 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.
