[REPORT] HBase Quarterly report Jan-Mar 2020

[Duo Zhang <zh...@apache.org>]

Hi all,

HBase submits a report to the ASF board once a quarter, to inform the board
about project health. I'm sending the report to the user@ and dev@ mailing
lists because you are the project, and for transparency. If you have any
questions about the report or the running of the project, you can post them
to any PMC member or committer, or send an email to private@hbase.apache.org
,
which every PMC member subscribes to.


*Special notice: Apache HBase was founded at 2010-4-21, so 2020-4-21 is our
10thanniversary!*

## Description:
Apache HBase is an open-source, distributed, versioned, non-relational
database. Apache HBase gives you low latency random access to billions of
rows
with millions of columns atop non-specialized hardware.

hbase-thirdparty is a set of internal artifacts used by the project to
mitigate the impact of our dependency choices on the wider ecosystem.

hbase-connectors is a collection of integration points with other projects.
The initial release includes artifacts for use with Apache Kafka and Apache
Spark.

hbase-filesystem contains HBase project-specific implementations of the
Apache
Hadoop FileSystem API. It is currently experimental and internal to the
project.

hbase-operator-tools is a collection of tools for HBase operators. Now it is
mainly for hosting HBCK2.

hbase-native-client is a client library in C/C++, in its early days.
