Yeah Sorry.

I formatted it nicely but it got lost while posting to the list

Subject: RE: Hadoop Summit EU HBase Meetup Review

Very interesting write up, but quite hard to read.

configuration, installation, complexity, documentation ... these can be
improved, no doubts, some other features (Inter DC replication and high
availability) are still behind of Cassandra's I think and this should be
prioritized by HBase community. I do not count MongoDB as a real contender -
its in another league and will become niche product for quick mash-ups of
web apps very soon. The real problem of HBase, I agree - its does not have
real corporate sponsor similar to Cassandra's DataStax.

Subject: Hadoop Summit EU HBase Meetup Review

We had Hadoop Summit Europe last week where we had an HBase Meetup. First we
had Enis talk about HBase Architectureand then Lars talked about some
interesting HBase Use CasesFinally, we opened it up to the public where we
had a frank discussion on the Uptake of HBase vs. other NoSQL DB's such as
Mongo and Cassandra. This wasn't about bashing other DB's, just
understanding how the spectrum of NoSQL DB's was leading to a
evaluation/production use of HBase. It was also partly based on the report
a-vs-hbase-239592Anyways these were the major points we discussed(Lars and
Jon Hsieh from Cloudera, Enis and Devaraj from Hortonworks contributed with
about input from 12 other users from the community)Documentation - Cassandra
has a better web page than HBase does. Even though HBase's documentation is
complete, finding the documentation is a bit hard. Installation - HBase is
hard to install for the newbie. I think there has been some effort to make
this more friendly by wrapping the master in RegionServersVendor Pushes -
Cassandra has DataStax, Pentaho pushes Mongo, Cloudera pushes Impala, MapR
is pushing their proprietary FS, IBM their own DB's. Even though HBase is
part of the Hadoop Ecosystem, there is no one vendor that is exclusively
pushing HBase to uptake by the community or even by the Hadoop
communityMessaging - HBase has been at the backend of a no. of negative
marketing by various vendors over things that were possibly true in the
past. For e.g. Lars mentioned that a certain vendor was incorrectly stating
that HBase has issue with SPOF even though this hasn't been true for quite
some time. Similarly, Jon mentioned that a certain slide where he was
talking about the complexity of HBase was taken out of context and shown as
a negative implementation of HBaseSQL based solutions - Even though there
are a no. of efforts to showcase that HBase has some SQL based interfaces
available like Phoenix, Impala & Hive(Albeit some issues), there is still
misconception that HBase is purely accessed via JavaSecurity in HBase - Even
though 0.98 has Security, it needs to be road tested.Some
recommendations:Push messaging out and make it more clear - Apache blogs,
Hortonworks Blogs, Cloudera blogsDocumentation - David Worms, who is a
consultant out of France, has volunteered to help make the website better.
You may want to reach out to him -
fr.linkedin.com/pub/david-worms/7/626/630Cost Calculator - Lars made a great
point of having a cost calculator ability to estimate the cost of various
operations. This makes it very likely by bigger organizations to pick and
choose HBase by understanding how they affect the bottom line

Update from Andrew -

"HBase has had strong security since 0.94 if not 0.92 - secure RPC and ACLs
at the table and column family level. We had these features before Cassandra
and even Accumulo.Why stuff like that gets lost is we are a bunch of
engineers not marketers. The trouble with messaging is someone has to write
it. Since it's a joyless job for most engineers, someone must be paid to do
it. "
