- Had a single node cluster with HDFS,YARN,MR and Zookeeper
- Try to add service Ambari Metrics
- Right after clicking Next on AssignMasters Page there comes a popup in AssignSlaves page that there is an issue with slaves assignment (pic1.png)
- Click Cancel on warning and check the details. Issue was:
{code}
At least 1 NodeManager components should be installed in cluster.
{code}
Try to choose NodeManager checkbox. But its disabled. User can still proceed by clicking Next and Continue Anyway. But the issue showed in popup and NodeManager checkbox being disabled doesnt look right
Could you please take a look at this scenario
