Wellington Chevreuil commented on HBASE-18738:
----------------------------------------------
So basically accepts reads, but backoff write requests. Internal subsystems
should be paused:
* Region Balancer
* AM
* LogRoll
* LogCleaner
* Flusher
* Scheduled Compactions
> Ride over HDFS 'safe mode' post-launch

> A coworker has an integration test that includes setting HDFS into 'safe
> mode' post-launch of the cluster. He finds that HBase just falls over. We
> should do better. We should be able to recognize the switch and going into
> stasis recovering once 'safe mode' has expired.
