HBase quarterly report Apr - June 2018

[Misty Linville <mi...@apache.org>]

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 pose them
to me or any other PMC member or committer, or send an email to
private@hbase.apache.org, which every PMC member subscribes to.

Thanks,
Misty

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.

ACTIVITY

HBaseCon US took place at Joseph McEnery Convention Center in San Jose, CA,
on June 18, 2018, simultaneous with PhoenixCon 2018. There were 180
attendees including 27 women. 120 of these attendees were there
specifically for HBaseCon. Some relevant quotes from the post-event
feedback:
- "I appreciate all talks, especially those showing unexpected use-cases or
developments in the community."
- "20 minute sessions are great since folks from the community can share
short stories of their experience using HBase."
- "Focus on technical context was refreshing"
Thanks again to Josh Elser and his team at Hortonworks for organizing and
facilitating HBaseCon.

An HBase meet-up took place in Beijing on June 6th in preparation for
