Subject Re: [DISCUSS] Looking to a 2.8.0 release
Date Wed, 25 Nov 2015 19:23:58 GMT
There are 40 odd incompatible changes in 3.x: https://issues.apache.org/jira/issues/?jql=project%20in%20%28HADOOP%2C%20YARN%2C%20HDFS%2C%20MAPREDUCE%29%20AND%20resolution%20%3D%20Fixed%20AND%20fixVersion%20%3D%203.0.0%20AND%20fixVersion%20not%20in%20%282.6.2%2C%202.6.3%2C%202.7.1%2C%202.7.2%2C%202.7.3%2C%202.8.0%29%20and%20%22Hadoop%20Flags%22%20in%20%28%22Incompatible%20change%22%29%20ORDER%20BY%20key%20ASC%2C%20due%20ASC%2C%20priority%20DESC%2C%20created%20ASC

Need to dig deeper on their impact. Clearly all my local shell scripts completely stopped
working, it will be good to have some bridging there to help users migrate.

Like I said before, I will spend more time on trunk only changes in order to kick-start a
3.x discussion.

What are the incompatible changes in the 2.x line that you are talking about?

in all the 2.x releases combined than in 3.x.
