Hi, we are currently facing issue as bellow, could you give us any suggestions? （We don’t know how to configure leader namenode and how to continue our instalization , could you give us any documents?）.
package version :
clusterj-hops-fix-7.6.10.jar hadoop-kms-3.2.0.4.jar hops-metadata-dal-impl-ndb-3.2.0.4.jar mysql-connector-java-8.0.11.jar
hadoop-common-3.2.0.4.jar hadoop-nfs-3.2.0.4.jar
hadoop-common-3.2.0.4-tests.jar hops-metadata-dal-3.2.0.4.jar
test step 
we now install ndb cluster on node23(bdb sql server node) , node24 ( ndb mamager node), node25 (ndb data node); and all of them are started;
Then we install dal and hadoop on node23;
Then we configure hops-ndb-config.properties;
and the last we use commond ‘start.dfs.sh’ to install hopsfs .
But as we don’t have any doc to follow that we have no idea with how to contine now:

Hope for your kindly suggestion!
