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.
