To bring it back to the original point and a high level view, the fact is that HBase is not Oracle, nor MySQL. It doesnt have multiple decades, and futhermore distributed systems are inherently more difficult (more failure cases) than single node DBs. Having said that, the grass is certainly not greener on the other side. I hear horror stories about every other nosqly technology out there. Without naming names, the bottom line is all new technologies need more care and feeding than your 30 year database server (with a 30 year old architecture to match btw). I know for a fact that multiple sites run huge HBase clusters without employing committers, so that fact lets me sleep at night.
Bugs get fixed, progress moves on. HBase is in a great place where every new release is better and offers something more than the previous, so I must urge everyone to upgrade. The .89 to 0.90 is a fairly trivial upgrade as well and rollbackable. Thanks for persistence.
