Note the Guava classes in the test directory for AsyncHBase. These are there
as AsyncHBase uses Guava >= 18 while HBase and the mini cluster use Guava 12.

[riak] Added new binding for Riak, based on the one created by Basho Technol…

[core] Add CoreWorkload.createOperationGenerator() for use in other w…

[couchbase2] Allow to log latency & runtime metrics.

[riak] R, W, etc. options are ignored for strong-consistent updates. So, it's useless to specify them.
[riak] Updated README.md with new considerations about benchmarks which use strong consistency model.

This changeset adds 2 config params which can be tweaked to enable
and print both the network latency and runtime metrics to the
configured logger.

[riak] Configured RiakKVClientTest.java to work with default bucket-type instead of creating a new one.

[travis] Added riak-admin commands to create and activate test bucket.

[riak] Added RiakKVClientTest.java

[riak] Added test unit.
[riak] Set eventual consistency as default in both README.md and riak.properties file, as strong consistency it's not the main model adopted by the db (check http://docs.basho.com/riak/kv/2.1.4/developing/app-guide/strong-consistency/ for further info).
[riak] Fixed getFields() function by transforming it into createResultHashMap(). This function creates the HashMap to give as result appropriately.
[riak] Removed scan transaction support for strong consistency model. 2i search is not allowed for this model, neither there is a suitable search mean to use to achieve a proper scan transaction.
[riak] Done minor fixes to code and comments.

Updated top level README for YCSB 0.8.0 release

[build] Added Oracle JDK 8 to .travis.yml

[riak] Done some code/comments cleanup.

[riak] Removed test unit as it only works with a local cluster installation (there is no Riak test or mock utility).
[riak] Packaged into com.yahoo.ycsb.db.riak.
[riak] Removed unused dependencies.
[riak] Bugfix for update() function that returned positive even with no nodes in the cluster.

[hbase10] Still too many threads #691.

[googlebigtable] Fix #697 by synchronizing on the static Config object

who's address does not change.

[hbase098] Add missing `writebuffersize` documentation and note to

[hbase10] Add instructions for testing against Google BigTable's HBase API.

[couchbase2] Add Support for Couchbase SDK 2.x

Eventually it would be nice to move this out into a proper generator with enums to
save space, but as users may have extended CoreWorkload and could be using the
"operationchooser" field, we'll just break it out into a static function so as to
avoid breaking anyone's code.

modify hbase-site.xml

Add documentation on how to use the hbase10 client with Google's
Bigtable.

[googlebigtable] Add a Google Bigtable binding for testing load using

The binding is based on the one created by Basho Technologies (available at https://github.com/basho-labs/YCSB/tree/master/riak).
[riak] Made compatible with the latest YCSB version.
[riak] Added strong consistency test support and made it default.
[riak] Added missing results return based on provided fields in scan/read functions.
[riak] Added TIME_OUT status return code for those transactions which take too long to complete.
[riak] Added flexible test parameter specification via customizable configuration file and command line options support.
[riak] Added test unit.
[riak] Removed unused Constants.java file.
[riak] Removed many unused function in the RiakUtils.java file.
[riak] Choosed to use executeAsync methods to resolve a bug that didn't allow the benchmark to end whenever one or more nodes of the cluster are killed.
[riak] Fixed license issues in all files.
[riak] Done some refinements to the code.

the native Protobuf GRPC based API.

[elasticsearch] Fix race condition

This commit fixes a race condition that exists between the shards being
ready to serve requests and the execution of the workload.

Fix broken synchronization meant to guard against over-creation
of cluster connection instances on startup when multiple threads.

[elasticsearch] Elasticsearch improvements
