Elliott Clark 6db1134cb7 HBASE-14211 Add more rigorous integration tests of splits
Summary:
Intgration tests don't currently have a lot of splits going on while there is IO.
This changes that by changing the split aglorithm and the max region hfile size. That should make things split more.

Additionally this allows ITBLL to start with just one region if hbase.test.pre-split-table is False.

Test Plan: Test on a cluster with ITBLL slow determinitic monkey and stress am monkey.

Summary: This test subclasses the BigLinkedList test. It takes two hbase clusters as arguments, sets up tables, sets up replication, and runs the BigLinkedList generator. The verification portion of the loop checks that the sink of the replication has the data and it is correct.

Test Plan: ran the test on my laptop and a small live cluster

Nick Dimiduk ab18158e60 HBASE-12728 buffered writes substantially less useful after removal of HTablePool (Solomon Duskis and Nick Dimiduk)
In our pre-1.0 API, HTable is considered a light-weight object that consumed by
a single thread at a time. The HTablePool class provided a means of sharing
multiple HTable instances across a number of threads. As an optimization,
HTable managed a "write buffer", accumulating edits and sending a "batch" all
at once. By default the batch was sent as the last step in invocations of
put(Put) and put(List<Put>). The user could disable the automatic flushing of
the write buffer, retaining edits locally and only sending the whole "batch"
once the write buffer has filled or when the flushCommits() method in invoked
explicitly. Explicit or implicit batch writing was controlled by the
setAutoFlushTo(boolean) method. A value of true (the default) had the write
buffer flushed at the completion of a call to put(Put) or put(List<Put>). A
value of false allowed for explicit buffer management. HTable also exposed the
buffer to consumers via getWriteBuffer().

The combination of HTable with setAutoFlushTo(false) and the HTablePool
provided a convenient mechanism by which multiple "Put-producing" threads could
share a common write buffer. Both HTablePool and HTable are deprecated, and
they are officially replaced in The new 1.0 API by Table and BufferedMutator.
Table, which replaces HTable, no longer exposes explicit write-buffer
management. Instead, explicit buffer management is exposed via BufferedMutator.
BufferedMutator is made safe for concurrent use. Where code would previously
retrieve and return HTables from an HTablePool, now that code creates and
shares a single BufferedMutator instance across all threads.
