* update mongodb-java-driver to latest 3.6.3
* add snappy for mongodb networkCompressor support

- module previously had an undeclared dependency on guava
- removed VisibleForTesting in favor of a comment
- removed Preconditions.checkNotNull in favor of NPE through use

closes #1136

* Geode 1.3 changed some of it's internals. The geode binding was using an
internal Geode class which means it won't compile against later versions
of geode.

* Based on review comments, leaving the geode version alone and adding
documentation to the README on how to change the version.

* Removed incubating from the geode name and website in README, because
geode is no longer incubating.

[hbase098, hbase10, hbase14, hbase20] HBase client updates

* [core] Drop JDK 7 Support

Sets compiler target to 1.8
Additionally removes openjdk7 from travis build-matrix
Fixes #1033

Additionally includes lexicographic reordering of binding-dependency properties in root pom

* [core] introduce baseclass for timeseries database bindings

This base-class parses the queries generated by TimeSeriesWorkload into a format
that's usable for simple consumption.
The format has been defined through the work done by Andreas Bader (@baderas) in
https://github.com/TSDBBench/YCSB-TS.

* [core] parse debug and test properties for all Timeseries databases

* [core] Add method to define possible tagKeys for Timeseries Workloads

Some TimeSeries Databases require a "schema" up front.
To generate said schema, the tag keys used by the workload are required.
This method should be centrally available for maintainability

* [core] Provide default implementation for  operation

TimeSeries databases only rarely support deleting data. As such we can generally assume
the operation to always return a Status.NOT_IMPLEMENTED. Similarly to updating that trivial
implementation does not need to be repeated in every TimeSeriesDatabase implementation

* [core] Address review

This adds a copyright header and significant amounts of javadoc for TimeseriesDB
Furthermore occurrences of Long have been largely replaced with the primitive long
Finally an overload for signed integer values has been added for insertions

When the TimeSeriesWorkload was run with fieldcount=1 and tagcount=1 and tagcardinality=1 the data generated always had the same timestamp. This commit fixes this behavior by forcing a tag rollover when there is only one tag. (#1091)

Switch Accumulo into multiple modules, one per minor release

[accumulo, accumulo1.6, accumulo1.7, accumulo1.8] switch Accumulo to minor version specific bindings.

* break out accumulo modules
* add deprecation warning
* switch travis to use short hostname to get around long hostname error.

closes #787

* remove mapkeeper and voldemort from command help, since we don't build them
* fix ordering of modules in root pom

closes #328

* [hbase10] Fix #701 by mimicking the same locks from the HBase 0.98 client in the HBase 10 client.

* Address CR comments, thanks @allanbank.

* Addressed the table lock.

* Restore the lock on the connection shutdown.

Also addressed @jasontedor review, thanks!

[core] Change the RemainingFormatter to reflect non-plural times, fix…

NOTE if you parse the standard out of YCSB, you'll be missing the "s" sometimes.

the existing YCSB API to generate time series data (numeric values associated
with timestamps).
See the TimeSeriesWorkload.java class Javadocs for details on how to use it
with a client and workloads/tsworkload_template for parameters.
Also add the BasicTSDB instance for printing/debugging the workloads.

* Google Datastore to use default credentials.

* Google Datastore to skip Index.

* Add oraclejdk9 to .travis.yml

* Upgrade maven-compiler-plugin

* Exclude jdk.tools from hadoop dependency

* Set minimum maven version to 3.1.0+, due to reqs for ES testing
* remove oracle jdk7 per travis-ci/travis-ci#7884
* Skip ES5 cluster spin-up if tests are skipped.
* Increase test heap for asynchbase binding from Travis 2048m to 4096m
  - https://docs.travis-ci.com/user/build-environment-updates/2017-09-06/
* temporarily remove the riak service on travis
  - currently fails w/o details
  - http://docs.basho.com/ fails to load, so I can't spin up a test node locally.

[elasticsearch,elasticsearch5] Add Elasticsearch 5.x binding

This commit removes an extraneous newline from
ElasticsearchRestClient.java.

This commit replaces some magic numbers (HTTP status codes) with
already-existing constants for this purpose.

This commit marks a field intended to be treated as a constant as final.

This commit removes duplicate test code from the elasticsearch5 and
elasticsearch5-rest test classes.

timestamps in a non-repeating random order.
Modify UnixEpochTimestampGenerator so that the random generator can
extend it.
