Very interesting write up, but quite hard to read.

configuration, installation, complexity, documentation ... these can be imp=
roved, no doubts, some other features (Inter DC replication and high availa=
bility) are still
behind of Cassandra's I think and this should be prioritized by HBase commu=
nity. I do not count MongoDB as a real contender - its in another league an=
d 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 corp=
orate 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 w=
e had Enis talk about HBase Architectureand then Lars talked about some int=
eresting 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 Mon=
go 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 o=
f HBase. It was also partly based on the report from InfoWorldhttp://podcas=
ts.infoworld.com/d/big-data/big-data-showdown-cassandra-vs-hbase-239592Anyw=
ays these were the major points we discussed(Lars and Jon Hsieh from Cloude=
ra, Enis and Devaraj from Hortonworks contributed with about input from 12 =
other users from the community)Documentation - Cassandra has a better web p=
age than HBase does. Even though HBase's documentation is complete, finding=
 the documentation is a bit hard. Installation - HBase is hard to install f=
or the newbie. I think there has been some effort to make this more friendl=
y by wrapping the master in RegionServersVendor Pushes - Cassandra has Data=
Stax, Pentaho pushes Mongo, Cloudera pushes Impala, MapR is pushing their p=
roprietary 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 upta=
ke by the community or even by the Hadoop communityMessaging - HBase has be=
en at the backend of a no. of negative marketing by various vendors over th=
ings that were possibly true in the past. For e.g. Lars mentioned that a ce=
rtain vendor was incorrectly stating that HBase has issue with SPOF even th=
ough this hasn't been true for quite some time. Similarly, Jon mentioned th=
at a certain slide where he was talking about the complexity of HBase was t=
aken out of context and shown as a negative implementation of HBaseSQL base=
d 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 v=
ia JavaSecurity in HBase - Even though 0.98 has Security, it needs to be ro=
ad 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 websit=
e better. You may want to reach out to him - fr.linkedin.com/pub/david-worm=
s/7/626/630Cost Calculator - Lars made a great point of having a cost calcu=
lator ability to estimate the cost of various operations. This makes it ver=
y 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 Cassand=
ra and even Accumulo.Why stuff like that gets lost is we are a bunch of eng=
ineers 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 i=
t. "
