             Summary: Restore ZKUtil.deleteRecursive in order to help compatibility of applications with 3.5 and 3.6
                 Key: ZOOKEEPER-3763
                 URL: https://issues.apache.org/jira/browse/ZOOKEEPER-3763
             Project: ZooKeeper
          Issue Type: Wish
          Components: java client
    Affects Versions: 3.6.0
            Reporter: Enrico Olivelli


In HerdDB project (https://github.com/diennea/herddb) we are using BookKeeper that in turn uses ZKUtil.deleteRecursive.

This is the issue on BookKeeper
https://github.com/apache/bookkeeper/issues/2292

This is the error:

java.lang.NoSuchMethodError: org.apache.zookeeper.ZKUtil.deleteRecursive(Lorg/apache/zookeeper/ZooKeeper;Ljava/lang/String;)V

Apart from trying to fix BookKeeper, we should take into consideration to restore that signature (adding some dummy method that calls the new one) in order to ease adoption of ZooKeeper 3.6.x

In fact it is very common that an application uses multiple ZooKeeper based libraries, like HBase, BookKeeper, Pulsar, Kafka...and the user cannot upgrade to 3.6 until every other dependency is able to work with 3.6.0.

If the fix is easy, like in this case, it is worth to help the community
