Karthik Kambatla updated YARN-1055:
-----------------------------------
Description:
Ideally, we would like to tolerate container, AM, RM failures. App recovery for
AM and RM currently relies on the max-attempts config; tolerating AM failures
requires it to be > 1 and tolerating RM failure/restart requires it to be = 1.
We should handle these two differently, with two separate configs.
was:In Hadoop-1, the job recovery on JT restart is configurable per-job. For
parity and its usefulness, we should have the same behavior in YARN as well.
