Purge ServiceException from Callable subclasses by pushing SE handling
up into the parent Callable class (varies by context but this is basic
patten). Allows us remove a bunch of boilerplate.
Do this in the public facing classes in particular (though if
an API has SE in it -- which a few do, this patch leaves these
untouched -- for now.) Make it so HBaseAdmin and HTable have no
direct pb imports (except for endpoint processor API).
Change a few of the HBaseAdmin calls to be retrying where comments
ask that we do retry rather than one time.
Purge TimeLimitedRpcController. Lets just have one override of RpcController.
M hbase-client/src/main/java/org/apache/hadoop/hbase/client/AbstractRegionServerCallable.java
Cleanup. Make it clear this is an odd class for async hbase intro.
M hbase-client/src/main/java/org/apache/hadoop/hbase/client/HTable.java
Refactor of RegionServerCallable allows me clean up a bunch of
boilerplate in here and remove protobuf references.
M hbase-client/src/main/java/org/apache/hadoop/hbase/client/HBaseAdmin.java
Purge protobuf references everywhere except a reference to a throw of a
ServiceException in method checkHBaseAvailable. I deprecated it in favor
of new available method (the SE is not actually needed)
M hbase-client/src/main/java/org/apache/hadoop/hbase/client/PayloadCarryingServerCallable.java
Move the RetryingTimeTracker instance in here from HTable.
Allows me to contain tracker and remove a repeated code in HTable.
M hbase-client/src/main/java/org/apache/hadoop/hbase/client/RegionServerCallable.java
Clean up move set up of rpc in here rather than have it repeat in HTable.
Allows me to remove protobuf references from a bunch of places.
M hbase-client/src/main/java/org/apache/hadoop/hbase/client/FlushRegionCallable.java
Make use of the push of boilerplate up into RegionServerCallable

TimeRangeTracker as point of contention when many threads reading a StoreFile
Fixes HBASE-16074 ITBLL fails, reports lost big or tiny families broken
scanning because of a side effect of a clean up in HBASE-15650 to make
TimeRange construction consistent exposed a latent issue in
TimeRange#compare. See HBASE-16074 for more detail.
Also change HFile Writer constructor so we pass in the TimeRangeTracker, if one,
on construction rather than set later (the flag and reference were not volatile
so could have made for issues in concurrent case). And make sure the construction
of a TimeRange from a TimeRangeTracer on open of an HFile Reader never makes a
bad minimum value, one that would preclude us reading any values from a file
(set min to 0)
M hbase-common/src/main/java/org/apache/hadoop/hbase/io/TimeRange.java
Call through to next constructor (if minStamp was 0, we'd skip setting
allTime=true). Add asserts that timestamps are not < 0 cos it messes
us up if they are (we already were checking for < 0 on construction but
assert passed in timestamps are not < 0).
M hbase-server/src/main/java/org/apache/hadoop/hbase/regionserver/HStore.java
Add constructor override that takes a TimeRangeTracker (set when flushing
but not when compacting)
M hbase-server/src/main/java/org/apache/hadoop/hbase/regionserver/Store.java
Add override creating an HFile in tmp that takes a TimeRangeTracker
M hbase-server/src/main/java/org/apache/hadoop/hbase/regionserver/StoreFile.java
Add override for HFile Writer that takes a TimeRangeTracker Take it on
construction instead of having it passed by a setter later (flags and
reference set by the setter were not volatile... could have been prob
in concurrent case)
M hbase-server/src/main/java/org/apache/hadoop/hbase/regionserver/TimeRangeTracker.java
Log WARN if bad initial TimeRange value (and then 'fix' it)
M hbase-server/src/test/java/org/apache/hadoop/hbase/regionserver/TestTimeRangeTracker.java
A few tests to prove serialization works as expected and that we'll get a bad min if not constructed properly.
M hbase-server/src/main/java/org/apache/hadoop/hbase/regionserver/ScanQueryMatcher.java
Handle OLDEST_TIMESTAMP explictly. Don't expect TimeRange to do it.
M hbase-server/src/test/java/org/apache/hadoop/hbase/regionserver/TestQueryMatcher.java
Refactor from junit3 to junit4 and add test for this weird case.
Instead of running the primary test in a separate thread and hoping it finishes in time, just run the test in the primary thread.

All ReplicationTableBase method's that need to access the Replication Table will block until it is created though.
Also refactored ReplicationSourceManager so that abandoned queue adoption is run in the background too so that it does not block HRegionServer initialization.

Refactor which makes a Handler type. Put all 'handler' stuff inside this
new type. Also make it so subclass can provide its own Handler type.

Invoking 'hbase hfile' inside a servlet raises several concerns. This
patch avoids invoking a separate process, and also adds validation that
the file being read is at least inside the HBase root directory.

Building on HBase-15883.
Now implementing the claim queues procedure within an HBase table.
Also added UnitTests to test claimQueue.
Peer tracking will still be performed by ZooKeeper though.
Also modified the queueId tracking procedure so we no longer have to perform scans over the Replication Table.
This does make our queue naming schema slightly different from ReplicationQueuesZKImpl though.

Changes how we do accounting of Connections to match how it is done in Hadoop.
Adds a ConnectionManager class. Adds new configurations for this new class.
"hbase.ipc.client.idlethreshold" 4000
"hbase.ipc.client.connection.idle-scan-interval.ms" 10000
"hbase.ipc.client.connection.maxidletime" 10000
"hbase.ipc.client.kill.max", 10
"hbase.ipc.server.handler.queue.size", 100
The new scheme does away with synchronization that purportedly would freeze out
reads while we were cleaning up stale connections (according to HADOOP-9955)
Also adds in new mechanism for accepting Connections by pulling in as many
as we can at a time adding them to a Queue instead of doing one at a time.
Can help when bursty traffic according to HADOOP-9956. Removes a blocking
while Reader is busy parsing a request. Adds configuration
"hbase.ipc.server.read.connection-queue.size" with default of 100 for
queue size.

Implemented ReplicationQueuesHBaseImpl that tracks WAL offsets and replication queues in an HBase table.
Only wrote the basic tracking methods, have not implemented claimQueue() or HFileRef methods yet.
Wrote a basic unit test for ReplicationQueueHBaseImpl that tests the implemented functions on a single Region Server
