Hi, [Speaking with HDFS in mind]
The 1.x line is the current stable/maintenance line that has features similar to that of 0.20.x before it, with append+sync and security features added on top of the pre-existing HDFS. The 2.x line carries several fixes and brand-new features (high availability, protobuf RPCs, federated namenodes, etc.) for HDFS, along with several performance optimizations, and is quite a big improvement over the 1.x line. The last release of 2.x, was 2.0.2, released a couple of months ago IIRC. This branch is very new, and is approaching full stability soon (Although, there's been no blocker kinda problems with HDFS at least, AFAICT). 3.x is an placeholder value for "trunk", it has not been branched for any release yet. We are currently focussed on improving the 2.x line further. On Wed, Nov 28, 2012 at 9:01 AM, sam liu <samliuhad...@gmail.com> wrote: > Hi Experts, > > Who can answer my following questions?
