stack afc1746757 HBASE-24034 [Flakey Tests] A couple of fixes and cleanups
hbase-rsgroup/src/test/java/org/apache/hadoop/hbase/rsgroup/TestRSGroupMajorCompactionTTL.java
 Remove spurious assert. Just before this it waits an arbitrary 10
 seconds. Compactions could have completed inside this time. The spirit
 of the test remains.

hbase-server/src/main/java/org/apache/hadoop/hbase/master/cleaner/HFileCleaner.java
 Get log cleaner to go down promptly; its sticking around. See if this
 helps with TestMasterShutdown

hbase-server/src/main/java/org/apache/hadoop/hbase/regionserver/wal/FSHLog.java
 We get a rare NPE trying to sync. Make local copy of SyncFuture and see
 if that helps.

hbase-server/src/test/java/org/apache/hadoop/hbase/client/TestAsyncRegionAdminApi.java
 Compaction  may have completed when not expected; allow for it.

hbase-server/src/test/java/org/apache/hadoop/hbase/client/TestBlockEvictionFromClient.java
 Add wait before testing. Compaction may not have completed. Let
 compaction complete before progressing and then test for empty cache.

hbase-server/src/test/java/org/apache/hadoop/hbase/master/TestMasterShutdown.java
 Less resources.

hbase-server/src/test/java/org/apache/hadoop/hbase/master/balancer/TestDefaultLoadBalancer.java
 Less resources.

hbase-server/src/test/java/org/apache/hadoop/hbase/regionserver/TestEndToEndSplitTransaction.java
 Wait till online before we try and do compaction (else request is
 ignored)

hbase-server/src/test/java/org/apache/hadoop/hbase/tool/TestCanaryTool.java
 Disable test that fails randomly w/ mockito complaint on some mac os
 x's.

TestMasterShutdown... fix NPE in RSRpcDispatcher... catch it and covert
to false and have master check for successful startup.

Restore behavior from before HBASE-21789 (hbase-2.2.0) where we convert
all exceptions to IOEs, even RuntimeExceptions. Actual fix is this change (in case
obscured by doc and lambda simplification):

     } catch (Throwable e) {
-      Throwables.propagateIfPossible(e, IOException.class);
+      // Throw if an IOE else wrap in an IOE EVEN IF IT IS a RuntimeException (e.g.
+      // a RejectedExecutionException because the hosting exception is shutting down.
+      // This is old behavior worth reexamining. Procedures doing merge or split
+      // currently don't handle RuntimeExceptions coming up out of meta table edits.
+      // Would have to work on this at least. See HBASE-23904.
+      Throwables.throwIfInstanceOf(e, IOException.class);

Master rpc server end point doesn't bind to localhost's
IP address by default. Instead, it looks up the hostname and
binds to the endpoint to which it resolves. MasterRegistry should
do the same when building the default server end point to talk to.

* HBASE-23604: Cleanup AsyncRegistry interface

- Cleans up the method names to make more sense and adds a little
more javadocs for context. In future patches we can revisit
the name of the actual class to make it more self explanatory.

- Does AsyncRegistry -> ConnectionRegistry rename.
"async" ness of the registry is kind of implicit based on
the interface contents and need not be reflected in the name.

This patch implements the RPCs needed for the meta information

code paths. HBASE-23305 builds on this to implement the client
side logic.

* HBASE-23281: Track meta region changes on masters

This patch adds a simple cache that tracks the meta region replica
locations. It keeps an eye on the region movements so that the
cached locations are not stale.

This information is used for servicing client RPCs for connections
that use master based registry (HBASE-18095). The RPC end points
will be added in a separate patch.

Make it so hbase:meta can be altered. TableState for hbase:meta
    was hardcoded ENABLED. Make it dynamic. State is now kept in
    current active Master. It is transient so falls back to default
    if Master crashes. Add to registry a getMetaTableState
    which reads mirrored state from zookeeper (NOT from Master and
    defaults ENABLED if no implementation or error fetching state).
    hbase:meta schema will be bootstrapped from the filesystem.
    Changes to filesystem schema are atomic so we should be ok if
    Master fails mid-edit (TBD). Undoes a bunch of guards that
    prevented our being able to edit hbase:meta.

Change its behavior so it will only look in hbase:meta
if the call to the super class turns up zero references.
Only then will it search hbase:meta for references to
'Unknown Servers'. Normal operation where we read Master
context is usual and sufficient. The scan of hbase:meta
is only for case where Master state has been corrupted
and we need to clear out 'Unknown Servers'.
