Hi Pradheep,
> I am trying to upgrade Zookeeper server and client from V3.4.6 to
> V3.5.5
Note that the latest version in the 3.5 series is 3.5.9; I would suggest
using that one.
That being said:
> When I upgrade, org.apache.zookeeper.data.Stat is not resolved as it is not
> the usual place as in 3.4.6
> We extensively use Stat to check if node exists in the zookeeper using
> checkExists() and use getStat().
> Without importing org.apache.zookeeper.data.Stat, all these are not getting

> Any reason why it is moved? But strangely I see it is being used in package

Yes. That (autogenerated) class used to be embedded in the main
ZooKeeper JAR:
$ jar tf zookeeper-3.4.6/dist-maven/zookeeper-3.4.6.jar
org/apache/zookeeper/data/Stat.class
org/apache/zookeeper/data/Stat.class
For 3.5, it was moved out of it, to zookeeper-jute-3.5.5.jar (with all
the other Jute-generated classes):
$ jar tf apache-zookeeper-3.5.5-bin/lib/zookeeper-3.5.5.jar
org/apache/zookeeper/data/Stat.class
$ jar tf apache-zookeeper-3.5.5-bin/lib/zookeeper-jute-3.5.5.jar
org/apache/zookeeper/data/Stat.class
org/apache/zookeeper/data/Stat.class
That new JAR should be added to your CLASSPATH.
HTH, -D
