Resolve kylin build cube error java.lang.NullPointerException
The reload metadata method mentioned on the Internet is not used at all.
This is caused by the node/kylin already existing on zookeeper. There is a problem with this node, resulting in no data. It is impossible to create a new node. Delete the node/kylin under zookeeper.
It's obviously zk's problem and he reported hive's mistake. Damn it, kylin is a real pit.
