Hadoop Security


Hi Experts,


I have a small question. Due to some deployment on 2 of the Linux servers, Our cluster's Key Trustee KMS & Key Trustee Server will have a downtime of few minutes during server reboot. 

I want to know what would be the impact on Hadoop services, since there is continuous data ingestion and extraction.


So if there is an impact then we can stop the service and also inform others.




@ateka_18 The downtime is better choice because KTS interacts with CDH cluster and failure/Down of KTS will hamper the CDH services hence the job.
