An error : Got error 4009 'Cluster Failure' from NDBCLUSTER

When I tried to login HOPSWORKS this morning, I encountered an error : Got error 4009 ‘Cluster Failure’ from NDBCLUSTER. After a few minutes this problem seemed to be fixed automatically.


As far as I know, NDBCLUSTER should be MySQL cluster. If this problem arises again, how do I find the cause? Which log can help me to analyze the cause of this problem? Has anyone had a similar problem? Any comments will be much appreciated.

It seems MySQL was temporarily unable to connect to the NDB storage engine. You will find the relevant logs in the /srv/hops/mysql-cluster/log folder

Hi @salman ,

Ok, thank you for your reply.
