KAFKA-4948: Failure in kafka.admin.DescribeConsumerGroupTest...
This test fails regularly when run on OSX (on my machine anyway). The fix
decreases the number of partitions in the consumer offsets topic allows it to
complete within the timeout.
As an aside I wondered why it was taking so long (regression??). This is
why:
- It takes 6 seconds to create the offsets topic (on OSX)
- It takes ~200ms to create each log
- It takes ~ 100ms to create each index file (time index + offset index)
- This time is spent on the line
[raf.setLength()](https://github.com/apache/kafka/blob/5fc530bc483db145e0cba3b63a57d6d6a7c547f2/core/src/main/scala/kafka/log/AbstractIndex.scala#L56)
This isn't an issue in practice, but at least we know this isn't a real
regression.
