Hi All,
We ran into a roadblock in our new Hadoop environment, migrating from 2.6 to
2.7. It was supposed to be an easy lift to get a YARN session but doesnt seem
like :) We definitely are using 2.7 binaries but it looks like there is a call
here to a private methos which screams runtime incompatibility.
Anyone has seen this and have pointers?
Thanks, Ashish
