Write Liveness Probes for Elassandra #99

Closed arturalbov closed 4 years ago

arturalbov commented 6 years ago

We faced the next situation: One node got stuck with java.lang.OutOfMemoryError: Java heap space error but container kept working. See logs logs-from-elassandra-in-elassandra-3.txt

So probably what we need is to check periodically if elassandra node is alive by kubernetes tool called liveness probe (k8s will restart it if node is not alive).

A ready-probe.sh script for k8s is now embedded in elassandra 5.5.0.21 docker image. See Scalable-Elassandra-deployment-on-Kubernetesfor usage in k8s configuration.
