@omkreddy if you have cycles, this is a 3.0 blocker. |

True, even better: contains. :)

nit: We could remove the extra block defined by the last { on this line.

Is it worth defining an inner helper method to avoid the repeated code here? Something like: assertPropery(config: ZKClientConfig, property: String, expectedValue: String).

That's a fair suggestion, I pushed a change along these lines.

We restore the 3.4.x/3.5.x behavior unless the caller has set the property (note that ZKConfig auto configures itself if certain system properties have been set). I added a unit test that fails without the change and passes with it. I also refactored the code to streamline the way we handle parameters passed to KafkaZkClient and ZooKeeperClient. See apache/zookeeper#1129 for the details on why the behavior changed in 3.6.0. Credit to @rondagostino for finding and reporting this issue. Reviewers: David Jacot <[email protected]>

ZooKeeper 3.6.0 changed the default configuration for JUTE_MAXBUFFER from 4 MB to 1 MB.
This causes a regression if Kafka tries to retrieve a large amount of data across many
znodes – in such a case the ZooKeeper client will repeatedly emit a message of the form
"java.io.IOException: Packet len <####> is out of range".
