CassandraRoleManager skipped default role setup: some nodes were not ready

Hi

I had this issue with my Cassandra 3.11.3 cluster.
'CassandraRoleManager skipped default role setup: some nodes were not ready'

Actually i didn't raised one of my nodes. The status was:

Datacenter: datacenter1

To solve it, i used the nodetool with 'removenode' method. Reference


Removing this node solved the problem for me.

Refusing to serve hidden directory, via 404 Error on AWS EC2

Refusing to serve hidden directory, via 404 Error

I got this error while running jupyter notebook inside my EC2

My Solution --> when i first run it, i was inside .jupyter directory.

I created my own 'workspace' directory, switching into it and then run it again the 'jupyter notbook'

Now all ok.


Hoped it helped,
