When a table or namespace is deleted, it would be nice to automatically
delete the quota on said table/NS. It's possible that not all people
would want this functionality so we can leave it up to the user to
configure this Observer.
A couple of variables and comments in which violation is incorrectly
used to describe what the code is doing. This was a hold over from early
implementation -- need to scrub these out for clarity.
* Expire region reports in the master after a timeout.
* Move regions in violation out of violation when insufficient
region size reports are observed.
The logic surrounding when a table and namespace quota both apply
to a table was incorrect, leading to a case where a table quota
violation which should have fired did not because of the less-strict
namespace quota.
Create some RPCs that can expose the in-memory state that the
RegionServers and Master hold to drive the space quota "state machine".
Then, create some hbase shell commands to interact with those.
The nuts-and-bolts of filesystem quotas. The Master must inform
RegionServers of the violation of a quota by a table. The RegionServer
must apply the violation policy as configured. Need to ensure
that the proper interfaces exist to satisfy all necessary policies.
This required a massive rewrite of the internal tracking by
the general space quota feature. Instead of tracking "violations",
we need to start tracking "usage". This allows us to make the decision
at the RegionServer level as to when the files in a bulk load request
should be accept or rejected which ultimately lets us avoid bulk loads
dramatically exceeding a configured space quota.
* Implement the RegionServer reading violation from the quota table
* Implement the Master reporting violations to the quota table
* RegionServers need to track its enforced policies
Adds a new Chore to the Master that analyzes the reports that are
sent by RegionServers. The Master must then, for all tables with
quotas, determine the tables that are violating quotas and move
those tables into violation. Similarly, tables no longer violating
the quota can be moved out of violation.
The Chore is the "stateful" bit, managing which tables are and
are not in violation. Everything else is just performing
computation and informing the Chore on the updated state.
Added InterfaceAudience annotations and clean up the QuotaObserverChore
constructor. Cleaned up some javadoc and QuotaObserverChore. Reuse
the QuotaViolationStore impl objects.
- internalRestoreSnapshot() returns future which completes by just getting proc_id from master. Changed it to wait for the procedure to complete.
- Refactor TestAsyncSnapshotAdminApi: Add cleanup() which deletes all tables and snapshots after every test run. Simplifies individual tests.

Test was failing on clusters with large number of servers or regions. Using commonly using config settings like some other tests seems to work.

With Apache parent pom v12 our remote-resources-plugin execution id was
shadowing the parent declaration, and our configuration would get run to
aggregate LICENSE files correctly. When upgrading to v18, apache changed
the execution id, so our configuration no longer gets used.
Add an explicit goal to our usage of the remote-resources-plugin and
change the name to something more descriptive and less likely to
conflict (either intentionally or not).

Use https for fetching d3 since builds.apache.org is also https. Otherwise d3 script is not loaded (unless browser is explicitly told to do so) and the fancy status markers are not drawn.

The default behavior for abort() method of StateMachineProcedure is changed to support aborting all procedures irrespective of if rollback is supported or not. Currently its observed that sometimes procedures may fail on a step which will be considered as retryable error as abort is not supported. As a result procedure may stuck in a endless loop repeating same step again.User should have an option to abort any stuck procedure and do clean up manually. Please refer to HBASE-18016 and discussion there.
