Jun Rao updated KAFKA-2174:
---------------------------
Status: In Progress (was: Patch Available)
Thanks for the patch. +1 and committed to trunk.
The patch handles the case when the full list of partitions is not returned in
TopicMetadataResponse. However, the broker should always return all partitions
in a topic in TopicMetadataResponse. We need to figure out why this is not
always true. So, leaving this jira open.
