I have a small hbase cluster with 1 namenode, 1 secondary namenode, 4 datanode. and the hbase master is on the same machine with namenode, 4 hbase slave on datanode machine. I found average requests per seconds is about 10,000. and the clusters crashed. and I found the reason is one datanode failed.
the datanode configuration is about 4 cpu core and 10GB memory is my cluster overloaded?
