YARN in 0.23 vs 2.0
We will be programming to the YARN resource manager and scheduler in an upcoming project, but I am unclear regarding its level of integration in each version.
Searching for, say, ApplicationSubmissionContext in versions of Hadoop, I see it in 0.23 and 2.0, but not in 1.0 or 1.1. Does this mean that YARN is available as the ASM/RM in both of these versions? Was 1.0 and 1.1 skipped over?
Thanks
john

Hi John,
You are correct that both 0.23 and 2.0 contain YARN, and that 1.x does not.
The (confusing) reason for this is that the 1.x line descends from the
0.20 line, while the 2.0 line descends from the 0.23 line.
