About how to contribute for zookeeper

[452914639]

Dear:
    When I read the zk source code from github. I have found some bugs.
    I have submitted a pull request and passed the test and ci.
    https://github.com/apache/zookeeper/pull/1017
This is my first attempt to contribute to zk, although it is only a very small 
problem, but I still insist on reading the source code of zk, I hope that there 
will be opportunities to participate in this great project in the future. So if 
there is anything wrong with the current process, please point out, thank you
