understanding the code base, patterns, threading, etc.S Ahmed 2012-05-17, 13:39
Greetings,
Other than reading the the source code, google papers, seda, etc. how does
someone get solid understanding of the code base?
Are there any high-level (or low level!) diagrams of sort that go over the
various components of hbase? (various read/write stages, gossip, etc.)
I'm guessing this is wishful thinking but I thought I'd ask :)

Well, the first answer is always the same: read the code! :)
Of course, sometimes it's difficult to get the high level concepts quickly that way (even with good docs, like the HBase code generally has). So I'd recommend seeing the upcoming talk by committer Lars Hofhansl at HBaseCon on Tuesday--that's exactly what it's about! It's called "HBase Internals".
If you're not attending, I'm sure they'll post slides (and maybe video?) afterwards.

I was afraid you were going to say that :)

Re: understanding the code base, patterns, threading, etc.Andrew Purtell 2012-05-17, 23:52
I'd also recommend Lars George's excellent "HBase The Definitive
Guide". It will give you a good conceptual foundation and an
understanding of how the API works. Then when you are tracing code
paths in the internals that act in service to the API, they will make
more sense.
