Description
On a server with enforceQuota=true, multi() transactions containing setData operations can throw NullPointerException during the quota check.
On the server side, this looks like:
java.lang.NullPointerException
at org.apache.zookeeper.server.ZooKeeperServer.checkQuota(ZooKeeperServer.java:2048)
at org.apache.zookeeper.server.PrepRequestProcessor.pRequest2Txn(PrepRequestProcessor.java:397)
[...]
On the client side, this is reflected as a MarshallingError:
org.apache.zookeeper.KeeperException$MarshallingErrorException: KeeperErrorCode = MarshallingError
at org.apache.zookeeper.KeeperException.create(KeeperException.java:104)
at org.apache.zookeeper.ZooKeeper.multiInternal(ZooKeeper.java:1758)
[...]
This is visibly due to the quota check trying to access node data by path from the PrepRequestProcessor without considering the collection of outstandingChanges. I have a patch in the works.
