The release numbering is so, AFAICT given the releases we've made: N.x.y x = minor releases with considerable amount of improvements y = mainly critical fix releases We have not yet branched the 1.2.0 release, and a vote is in progress for the 1.1.1 release. I expect, if you want to pick one up very soon, you may choose 1.1.1 which should be made officially available in a week or two. Note that we do care not to break compatibility within an N line. Meaning, upgrading from a 1.x1 to 1.x2 release is a trivial effort equal to a restart of cluster (no metadata upgrades). > For 2.x line: > - Will its stable release contain all fixes and features of 1.x line?

The next release, 2.0.3, is yet to be finalized, but I expect a vote to be called sometime soon. I am unsure if it will still be tagged unstable or not. From my experience so far of users/customers running 2.x based HDFS (with or without HA), I've hardly seen any major issues that may shed bad light on its stability. > Sam Liu <snip> -- Harsh J
