Michael Stack 890d92a90c HBASE-17908 Upgrade guava
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

Josh Elser e5ea457054 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.

Michael Stack 3975bbd008 HBASE-14614 Procedure v2 - Core Assignment Manager (Matteo Bertozzi) Move to a new AssignmentManager, one that describes Assignment using a State Machine built on top of ProcedureV2 facility.
This doc. keeps state on where we are at w/ the new AM:
https://docs.google.com/document/d/1eVKa7FHdeoJ1-9o8yZcOTAQbv0u0bblBlCCzVSIn69g/edit#heading=h.vfdoxqut9lqn
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.

    Details:

    M hbase-client/src/main/java/org/apache/hadoop/hbase/ClusterStatus.java
    Takes List of regionstates on construction rather than a Set.
    NOTE!!!!! This is a change in a public class.

    M hbase-client/src/main/java/org/apache/hadoop/hbase/master/RegionState.java
    Purge old overlapping states: PENDING_OPEN, PENDING_CLOSE, etc.

    M hbase-procedure/src/main/java/org/apache/hadoop/hbase/procedure2/Procedure.java
    Lots of doc on its inner workings. Bug fixes.

    M hbase-procedure/src/main/java/org/apache/hadoop/hbase/procedure2/ProcedureExecutor.java
    Log and doc on workings. Bug fixes.

    A hbase-procedure/src/main/java/org/apache/hadoop/hbase/procedure2/RemoteProcedureDispatcher.java
    Dispatch remote procedures every 150ms or 32 items -- which ever
    happens first (configurable). Runs a timeout thread. This facility is
    not on yet; will come in as part of a later fix. Currently works a
    region at a time. This class carries notion of a remote procedure and of a buffer full of these.

    "hbase.procedure.remote.dispatcher.delay.msec" with default = 150ms
    "hbase.procedure.remote.dispatcher.max.queue.size" with default = 32

    M hbase-client/src/main/java/org/apache/hadoop/hbase/shaded/protobuf/ProtobufUtil.java
    Add in support for merge. Remove no-longer used methods.

    M hbase-protocol-shaded/src/main/protobuf/Admin.proto b/hbase-protocol-shaded/src/main/protobuf/Admin.proto
    Add execute procedures call ExecuteProcedures.

    M hbase-protocol-shaded/src/main/protobuf/MasterProcedure.proto
    Add assign and unassign state support for procedures.

    M hbase-server/src/main/java/org/apache/hadoop/hbase/client/VersionInfoUtil.java
    Adds getting RS version out of RPC
    Examples: (1.3.4 is 0x0103004, 2.1.0 is 0x0201000)

    M hbase-server/src/main/java/org/apache/hadoop/hbase/master/HMaster.java
    Remove periodic metrics chore. This is done over in new AM now.
    Replace AM with the new. Host the procedures executor.

    M hbase-server/src/main/java/org/apache/hadoop/hbase/master/MasterMetaBootstrap.java b/hbase-server/src/main/java/org/apache/hadoop/hbase/master/MasterMetaBootstrap.java
    Have AMv2 handle assigning meta.

    M hbase-server/src/main/java/org/apache/hadoop/hbase/master/MasterRpcServices.java
    Extract version number of the server making rpc.

    A hbase-server/src/main/java/org/apache/hadoop/hbase/master/assignment/AssignProcedure.java
    Add new assign procedure. Runs assign via Procedure Dispatch.
    There can only be one RegionTransitionProcedure per region running at the time,
    since each procedure takes a lock on the region.

Revert a mistaken commit!!!

This reverts commit dc1065a85d.
2017-05-24 23:31:36 -07:00
Michael Stack dc1065a85d HBASE-14614 Procedure v2 - Core Assignment Manager (Matteo Bertozzi)
Move to a new AssignmentManager, one that describes Assignment using
a State Machine built on top of ProcedureV2 facility.

This doc. keeps state on where we are at w/ the new AM:
https://docs.google.com/document/d/1eVKa7FHdeoJ1-9o8yZcOTAQbv0u0bblBlCCzVSIn69g/edit#heading=h.vfdoxqut9lqn
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.

Details:

Josh Elser d671a1dbc6 HBASE-17955 Various reviewboard improvements to space quota work
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.

Josh Elser a8460b8bad HBASE-17794 Swap "violation" for "snapshot" where appropriate

Josh Elser 34ba143fc8 HBASE-17001 Enforce quota violation policies in the RegionServer
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.

Josh Elser 98b4181f43 HBASE-16999 Implement master and regionserver synchronization of quota state

* Implement the Master reporting violations to the quota table

2017-05-22 13:41:35 -04:00
Josh Elser 533470f8c8 HBASE-16998 Implement Master-side analysis of region space reports
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.
