We are looking to autoscale hadoop cluster up/down using time based mode. We are able to upscale the cluster successfully but the downscale does not get triggered automatically. But if we use remove nodes feature then it works fine. The host group which we are trying to downscale does not contain datanodes.
Can someone help us if we are not doing something correctly? I am attaching screenshot of alerts, scaling policies , cluster scaling configuration and history.
You can take a look at the logs
docker logs -f cbreak_periscope_1
There are some restrictions when you cannot do a downscale, for example you cannot scale down below certain number of nodes. The log should tell you why the downscale was not triggered.
