Hiya folks,
As we're wrapping up on the current set of features listed in
HBASE-16961 for tracking and limiting the HDFS space used by HBase
tables and namespaces, I wanted to present a doc that outlines an
approach to tracking snapshots in the context of space quotas.
As most operators know, snapshots can be a cause of the "why is my HDFS
full??" category of errors. Obviously, this makes it a logical next-step
to track. The following docs present (what I think is) a fairly simple
extension to the existing design/implementation as outlined in HBASE-16961.
For those with the cycles to give it some thought/feedback, I'd be
over-joyed to receive it! Thanks in advance to our Clay, Enis, and
Devaraj for the feedback they've provided already.
As always, your choice of Google doc[1] and PDF[2] are available.
