Thanks Gopal for this configuration. I find the configuration "tez.am.container.idle.release-timeout-min.millis" works to disable container idle release thought it's not recommended.

There's another config which can let you run it without losing containers (at least if you know how many you want to keep). tez.am.session.min.held-containers This will hold <n> containers with no timeout and try to spread them across as many nodes as possible (to serve locality better). However, this needs to set into the tez-site.xml being a tez.am.* parameter. Cheers, Gopal
