We have 3 cluster nodes MapR. All 3 nodes have zookeeper, and the 1st node has CLDB, a web server and ResourceManager, except for zookeeper.
The cluster is up and running, but the first node declined yesterday, after which the service is CLDBnot suitable.
The service MFSalso does not work on the same node.
We tried to get the last era of cldb by specifying the maprcli dump zkinfo -json command, but this gives me an error:
"Unable to obtain the ZooKeeper connection string".
Warden magazine also gives the same zookeeper error.
I already checked the zookeeper qstatus and it shows the launch.
We guaranteed that the first node has zookeeper as the leader and the other 2 nodes are followers, but restarting cldb gives the same error, and the MFS service also does not start.
I don’t know how to debug and how to start a cluster.
thank,
