---------------------------------
Summary: Remove duplicate check to metadataFetchInProgress
Key: KAFKA-2090
URL: https://issues.apache.org/jira/browse/KAFKA-2090
Project: Kafka
Issue Type: Improvement
Reporter: Tim Brooks
Priority: Minor
In the NetworkClient class on a call to poll() there are three checks
(timeToNextMetadataUpdate, timeToNextReconnectAttempt, waitForMetadataFetch)
made to see if a metadata update should be made. If all of these == 0 then an
update is performed.
However, in the if block a second check is made to metadataFetchInProgress.
This only make sense in a multithreaded environment. However, as the variable
is not volatile I suspect this is not the case.
