Review request for hbase, stack, Nicolas, Karthik Ranganathan, and Kannan
Muthukkaruppan.
Changes
-------
Minor cleanup.
Summary
-------
Pulls compaction file selection code into new interface and makes it so it's
configurable. Currently is globally configurable but should be easy to make it
per-family setting.
Also makes the algorithm standalone and testable.
Includes a new compaction algorithm based on a new config param
'compactionForce'. See javadoc in compaction classes for explanation.
Big test included for new algorithm.
Also the TestCompact class includes a neat new way for us to compare compaction
algorithms. You specify a bunch of input paramaters and then it runs a
simulation and generates statistics. The output looks like:
-----
Ran test
-----
numPuts=1000000
putSizeRange=1.0KB to 10.0KB
numPutsPerGet=10
flushSizeRange=64.0MB to 256.0MB
max=10, threshold=3, force=6, factor=0.5
-----
-----
Final Result
-----
files=82.2MB, 2.9GB, 898.3MB, 1.3GB
memstoreSize=100.8MB
totalSize=5.1GB
totalThroughput=18.2GB
averageFilesPerGet=3.25622
This addresses bug HBASE-2462.

TestCompact is passing. Have not run test suite.
