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

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.

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 from InfoWorldhttp://podcasts.infoworld.com/d/big-data/big-data-showdown-cassandr 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.
