Subject Re: Spark on Yarn, is it possible to manually blacklist nodes before running spark job?
Date Wed, 23 Jan 2019 22:09:22 GMT
Serga, can you explain a bit more why you want this ability?
If the node is really bad, wouldn't you want to decomission the NM entirely?
If you've got heterogenous resources, than nodelabels seem like they would
be more appropriate -- and I don't feel great about adding workarounds for
the node-label limitations into blacklisting.

I don't want to be stuck supporting a configuration with too limited a use

(may be better to move discussion to so its better archived,
I'm responding here in case you aren't watching that issue)
