Aaron T. Myers commented on HDFS-2430:
--------------------------------------
bq. Per HDFS-208 might be worth considering other warnings to log eg if there's
only a single redundant resource left. Could also standardize the
location/format of the log check and output to make life easier for monitoring
tools. Ditto for metrics (feel free to address in another jira).
I've filed HDFS-2613 to address this.
> The number of failed or low-resource volumes the NN can tolerate should be

> effectively hard-coded at 1. It would be nice if this were configurable.
