kylin的mapreduce任务都会去尝试连接zookeeper,但是是这样连接的:2015-11-13 12:37:37,886 INFO [main-SendThread(localhost:2181)] org.apache.zookeeper.ClientCnxn: Opening socket connection to server localhost/127.0.0.1:2181. Will not attempt to authenticate using SASL (unknown error),使用的是localhost并不是zookeeper集群中的机器,所以mapreduce如果datanode与zookeeper集群在一个上就能成功,否则失败,这一阶段发生在Convert Cuboid Data to HFile 阶段
