Add in hbase-thirdparty hbase-shaded-netty instead.
s/io.netty/org.apache.hadoop.hbase.shaded.io.netty/ everywhere in hbase.
Also set a system property when running tests and when starting
hbase; required by netty so can find the relocation files in the
bundled .so.
Contains the following commits:
HBASE-17748 Include HBase snapshots in space quotas
Introduces a new Chore in the Master which computes the size
of the snapshots included in a cluster. The size of these
snapshots are included in the table's which the snapshot was created
from HDFS usage.
Includes some test stabilization, trying to make the tests more
deterministic by ensuring we observe stable values as we know
that those values are mutable. This should help avoid problems
where size reports are delayed and we see an incomplete value.
HBASE-17752 Shell command to list snapshot sizes WRT quotas
HBASE-17840 Update hbase book to space quotas on snapshots
Other changes:
- Update corresponding tests in TestAdmin2. Removed tests centered around serverName part of old functions.
- Remove dead functions from ProtobufUtil and ServerManager
- Rename closeRegion* functions in HBTU to unassignRegion*

Selective add of dependency on hbase-thirdparty jars.
Update to READMEs on how protobuf is done (and update to refguide).
Removed all checked in generated protobuf files. They are generated
on the fly now as part of mainline build.
Pull in guava 22.0 by using the shaded version up in new hbase-thirdparty project.
In poms, exclude guava everywhere except on hadoop-common. Do this so
we minimize transitive includes. hadoop-common is needed because hadoop
Configuration uses guava doing preconditions.
Everywhere we used guava, instead use shaded so fix a load of imports.
Stopwatch API changed as did hashing and toStringHelper which is now
in MoreObjects class. Otherwise, minimal changes to come up on 22.0
hbase-thirdparty jars. Update to READMEs on how protobuf is done (and update to
refguide) Removed all checked in generated protobuf files. They are generatedon
the fly now as part of mainline build.
Revert "Revert "HBASE-18266 Create static empty byte array to save memory (Ben Epstein)""
... i.e. a reapply but with correct JIRA this time.
This reverts commit 3a0db474a2.
This issue adds comments and a sort so system tables are queued first
(which will ensure they go out first). This should be good enough
along w/ existing scheduling mechanisms to ensure system/meta get
assigned first.

Includes list of tests disabled by this patch with reasons why.
Based on patches from Matteos' repository and then fix up to get it all to pass cluster
tests, filling in some missing functionality, fix of findbugs, fixing bugs, etc..
including:
1. HBASE-14616 Procedure v2 - Replace the old AM with the new AM.
The basis comes from Matteo's repo here:
689227fcbf
Patch replaces old AM with the new under subpackage master.assignment.
Mostly just updating classes to use new AM -- import changes -- rather
than the old. It also removes old AM and supporting classes.
See below for more detail.
2. HBASE-14614 Procedure v2 - Core Assignment Manager (Matteo Bertozzi)
3622cba4e3
Adds running of remote procedure. Adds batching of remote calls.
Adds support for assign/unassign in procedures. Adds version info
reporting in rpc. Adds start of an AMv2.
3. Reporting of remote RS version is from here:
ddb4df3964.patch
4. And remote dispatch of procedures is from:
186b9e7c4d
5. The split merge patches from here are also melded in:
9a3a95a2c2
and d6289307a0
We add testing util for new AM and new sets of tests.
Does a bunch of fixup on logging so its possible to follow a procedures' narrative by grepping
procedure id. We spewed loads of log too on big transitions such as master fail; fixed.
Fix CatalogTracker. Make it use Procedures doing clean up of Region data on split/merge.
Without these changes, ITBLL was failing at larger scale (3-4hours 5B rows) because we were
splitting split Regions among other things (CJ would run but wasn't
taking lock on Regions so havoc).
Added a bunch of doc. on Procedure primitives.
Added new region-based state machine base class. Moved region-based
state machines on to it.
Found bugs in the way procedure locking was doing in a few of the
region-based Procedures. Having them all have same subclass helps here.
Added isSplittable and isMergeable to the Region Interface.
Master would split/merge even though the Regions still had
references. Fixed it so Master asks RegionServer if Region
is splittable.
Messing more w/ logging. Made all procedures log the same and report
the state the same; helps when logging is regular.
Rewrote TestCatalogTracker. Enabled TestMergeTableRegionProcedure.
Added more functionality to MockMasterServices so can use it doing
standalone testing of Procedures (made TestCatalogTracker use it
instead of its own version).
Add to MasterServices ability to wait on Master being up -- makes
it so can Mock Master and start to implement standalone split testing.
Start in on a Split region standalone test in TestAM.
Fix bug where a Split can fail because it comes in in the middle of
a Move (by holding lock for duration of a Move).
Breaks CPs that were watching merge/split. These are run by Master now
so you need to observe on Master, not on RegionServer.

Most notable change is to cache SpaceViolationPolicyEnforcement objects
in the write path. When a table has no quota or there is not SpaceQuotaSnapshot
for that table (yet), we want to avoid creating lots of
SpaceViolationPolicyEnforcement instances, caching one instance
instead. This will help reduce GC pressure.
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.
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.
Change-Id: Idc30fb699db32d58fd0f60da220953a430f1d3cc
Added metrics for RecoverableZooKeeper related to specific exceptions,
total failed ZooKeeper API calls and latency histograms for read,
write and sync operations. Also added unit tests for the same. Added
service provider for the ZooKeeper metrics implementation inside the
hadoop compatibility module.
