2018-08-20 16:59:20,603 [myid:3] - WARN  [NIOServerCxn.Factory:0.0.0.0/0.0.0.0:2181:NIOServerCnxnFactory@193] - Too many connections from /192.168.58.11 - max is 60
2018-08-20 16:59:20,619 [myid:3] - WARN  [NIOServerCxn.Factory:0.0.0.0/0.0.0.0:2181:NIOServerCnxnFactory@193] - Too many connections from /192.168.58.11 - max is 60

搜索后,在ambari界面上添加如下参数[maxClientCnxns],问题解决:
