Karam Singh commented on MAPREDUCE-3846:
----------------------------------------

It also appeared for me in case when I killed AM at 150 secs, when more than 13000 out of 16800 maps were ran
Marking it critical

> [~karams] found this while testing AM restart/recovery feature. After the first generation AM crashes (manually killed by kill -9), the second generation AM starts, but hangs after a while.
