Adding a Monitor page to the MiniAccumuloCluster was quite easy once I
looked at the code and using the Impl classes instead of the
Interfaces.
MiniAccumuloConfigImpl miniAccumuloConfig = new
MiniAccumuloConfigImpl(new File("/accumulo"), "password");
MiniAccumuloClusterImpl accumulo = new
MiniAccumuloClusterImpl(miniAccumuloConfig);
accumulo.start();
accumulo.exec(Monitor.class);
Here is the process tree on my laptop with 20 TServers in my Docker instance.
MiniAccumuloConfigImpl miniAccumuloConfig = new
MiniAccumuloConfigImpl(new File("/accumulo"), "password");root
