-------------------------------------
Summary: YARN kills Flink TM containers due to memory overuse
(outside heap/offheap)
Key: FLINK-3151
URL: https://issues.apache.org/jira/browse/FLINK-3151
Project: Flink
Issue Type: Bug
Components: TaskManager
Affects Versions: 0.10.1, 1.0.0
Environment: 48 cores
Reporter: Robert Metzger
Priority: Blocker
A Flink user who's running Flink on YARN with 1 processing slot, 2 GB of TM
memory on a machine with 48 reported CPU cores is running into issues with TM
containers being killed due to memory overuse.
Setting the YARN memory cutoff to 0.5 resolves the problem, but its not really
a feasible approach.
Another solution to the problem was downgrading netty again from 4.0.31.Final
to 4.0.27.Final resolved the issue.
We upgraded Netty between 0.9 and 0.10.
Most likely netty changed its behavior between the releases.
