[26/26] hbase git commit: 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.
Posted by st...@apache.org.
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:
https://github.com/matteobertozzi/hbase/commit/689227fcbfe8e6588433dbcdabf4526e3d478b2e
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)
https://github.com/matteobertozzi/hbase/commit/3622cba4e331d2fc7bfc1932abb4c9cbf5802efa
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:
https://github.com/matteobertozzi/hbase/commit/ddb4df3964e8298c88c0210e83493aa91ac0942d.patch
4. And remote dispatch of procedures is from:
https://github.com/matteobertozzi/hbase/commit/186b9e7c4dae61a79509a6c3aad7f80ec61345e5
5. The split merge patches from here are also melded in:
https://github.com/matteobertozzi/hbase/commit/9a3a95a2c2974842a4849d1ad867e70764e7f707
and https://github.com/matteobertozzi/hbase/commit/d6289307a02a777299f65238238a2a8af3253067
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/HRegionInfo.java
Add utility getShortNameToLog
M hbase-client/src/main/java/org/apache/hadoop/hbase/client/ConnectionImplementation.java
M hbase-client/src/main/java/org/apache/hadoop/hbase/client/ShortCircuitMasterConnection.java
Add support for dispatching assign, split and merge processes.
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.threadpool.size" with default = 128
"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.
D hbase-server/src/main/java/org/apache/hadoop/hbase/master/AssignCallable.java
D hbase-server/src/main/java/org/apache/hadoop/hbase/master/AssignmentManager.java
D hbase-server/src/main/java/org/apache/hadoop/hbase/master/BulkAssigner.java
D hbase-server/src/main/java/org/apache/hadoop/hbase/master/GeneralBulkAssigner.java b/hbase-server/src/main/java/org/apache/hadoop/hbase/master/GeneralBulkAssigner.java
Remove these hacky classes that were never supposed to live longer than
a month or so to be replaced with real assigners.
D hbase-server/src/main/java/org/apache/hadoop/hbase/master/RegionStateStore.java
D hbase-server/src/main/java/org/apache/hadoop/hbase/master/RegionStates.java
D hbase-server/src/main/java/org/apache/hadoop/hbase/master/UnAssignCallable.java
A hbase-server/src/main/java/org/apache/hadoop/hbase/master/assignment/AssignmentManager.java
A procedure-based AM (AMv2).
TODO
- handle region migration
- handle meta assignment first
- handle sys table assignment first (e.g. acl, namespace)
- handle table priorities
"hbase.assignment.bootstrap.thread.pool.size"; default size is 16.
"hbase.assignment.dispatch.wait.msec"; default wait is 150
"hbase.assignment.dispatch.wait.queue.max.size"; wait max default is 100
"hbase.assignment.rit.chore.interval.msec"; default is 5 * 1000;
"hbase.assignment.maximum.attempts"; default is 10;
A hbase-server/src/main/java/org/apache/hadoop/hbase/master/assignment/MoveRegionProcedure.java
Procedure that runs subprocedure to unassign and then assign to new location
A hbase-server/src/main/java/org/apache/hadoop/hbase/master/assignment/RegionStateStore.java

+ * <p>Procedures are run by a {@link ProcedureExecutor} instance. They are submitted and then
+ * the ProcedureExecutor keeps calling {@link #execute(Object)} until the Procedure is done.
+ * Execute may be called multiple times in the case of failure or a restart, so code must be
+ * idempotent. The return from an execute call is either: null to indicate we are done;
+ * ourself if there is more to do; or, a set of sub-procedures that need to
+ * be run to completion before the framework resumes our execution.
*

+ * <p>The ProcedureExecutor keeps its
+ * notion of Procedure State in the Procedure itself; e.g. it stamps the Procedure as INITIALIZING,
+ * RUNNABLE, SUCCESS, etc. Here are some of the States defined in the ProcedureState enum from
+ * protos:
+ *<ul>
+ * <li>{@link #isFailed()} A procedure has executed at least once and has failed. The procedure
+ * may or may not have rolled back yet. Any procedure in FAILED state will be eventually moved
+ * to ROLLEDBACK state.</li>
+ *
+ * <li>{@link #isSuccess()} A procedure is completed successfully without exception.</li>
+ *
+ * <li>{@link #isFinished()} As a procedure in FAILED state will be tried forever for rollback, only
+ * condition when scheduler/ executor will drop procedure from further processing is when procedure
+ * state is ROLLEDBACK or isSuccess() returns true. This is a terminal state of the procedure.</li>
+ *
+ * <li>{@link #isWaiting()} - Procedure is in one of the two waiting states
+ * ({@link ProcedureState#WAITING}, {@link ProcedureState#WAITING_TIMEOUT}).</li>
+ *</ul>
+ * NOTE: This states are of the ProcedureExecutor. Procedure implementations in turn can keep
+ * their own state. This can lead to confusion. Try to keep the two distinct.
+ *
+ * <p>rollback() is called when the procedure or one of the sub-procedures
+ * has failed. The rollback step is supposed to cleanup the resources created
+ * during the execute() step. In case of failure and restart, rollback() may be
+ * called multiple times, so again the code must be idempotent.
+ *
+ * <p>Procedure can be made respect a locking regime. It has acqure/release methods as
+ * well as an {@link #hasLock(Object)}. The lock implementation is up to the implementor.
+ * If an entity needs to be locked for the life of a procedure -- not just the calls to
+ * execute -- then implementations should say so with the {@link #holdLock(Object)}
+ * method.
+ *
