Project: ZooKeeper
Issue Type: Bug

Affects Versions: 3.6.3

Reporter: Antonio Antonucci
Hi everybody, I am having an issue zookeeper 3.6.3
Two things to highlight:
* 1) The issue I am having is:
INFO Refusing session request for client /192.168.1.163:42230 as it has seen
zxid 0xa25 our last zxid is 0x23 client must try another server
(org.apache.zookeeper.server.ZooKeeperServer)
>> Initially the zookeeper datadir was configured as per default under /tmp.
>> Following this error I have moved the datadir under /opt/zookeeper, deleted
>> all the logs directory content and rebooted the server.
>> Soon after the rebooting, the errror message was:
INFO Refusing session request for client /192.168.1.163:41738 as it has seen
zxid 0xa25 our last zxid is 0x0 client must try another server
(org.apache.zookeeper.server.ZooKeeperServer)
>> However once I started Kafka, the error went back to the original "... it
>> has seen zxid 0xa25 our last zxid is 0x23.. "
>> I don't know how to sort this out
* 2) I have tried to run the ZkWorkarounderMultiThreaded java file, however I
am getting the following errors:
ZkWorkarounderMultiThreaded.java
ZkWorkarounderMultiThreaded.java:40: error: cannot access ACL
zk.create(path, data, Ids.OPEN_ACL_UNSAFE, CreateMode.PERSISTENT);
^

4 errors
error: compilation failed
>> I have only included the following lines in the java code, however I guess
>> things have changed with zk 3.6.3?
package core.framework.zookeeper;
import java.io.IOException;
import java.util.Date;
import java.util.List;
import java.util.concurrent.CountDownLatch;
import org.apache.zookeeper.CreateMode;
import org.apache.zookeeper.WatchedEvent;
import org.apache.zookeeper.Watcher;
import org.apache.zookeeper.Watcher.Event.KeeperState;
import org.apache.zookeeper.ZooDefs.Ids;
import org.apache.zookeeper.ZooKeeper;
import org.apache.zookeeper.KeeperException;
>> I don't literally know how to sort this out.
>> Can somebody help me please?
