------------------------------
Summary: java producer may miss an available partition
Key: KAFKA-1984
URL: https://issues.apache.org/jira/browse/KAFKA-1984
Project: Kafka
Issue Type: Bug
Affects Versions: 0.8.2.0
Reporter: Jun Rao
Assignee: Jun Rao
In Partitioner, we cycle through each partition to find one whose leader is
available. However, since the counter is shared among different caller threads,
the logic may not iterate through every partition. The impact is that we could
return an unavailable partition to the caller when there are partitions
available. If the partition is unavailable for a long time, the producer may
block due to bufferpool being full.
