----------------------------------------
Summary: Differences between documentation and implementation for
taskmanager.memory.network.max
Key: FLINK-23837
URL: https://issues.apache.org/jira/browse/FLINK-23837
Project: Flink
Issue Type: Bug
Affects Versions: 1.12.0
Reporter: Wawrzyniec Nowak
The default value for taskmanager.memory.network.max is [documented
|https://ci.apache.org/projects/flink/flink-docs-release-1.13/docs/deployment/config/#taskmanager-memory-network-max]
as 1gb but in the logs it says that
{code:java}
org.apache.flink.runtime.taskexecutor.TaskExecutorResourceUtils - The
configuration option taskmanager.memory.network.max required for local
execution is not set, setting it to its default value 64mb.
{code}
And it looks like 64mb is actually the default:
https://github.com/apache/flink/blob/9e8c551958f30d5b54cbb26d2a232d96e1e0988c/flink-runtime/src/main/java/org/apache/flink/runtime/taskexecutor/TaskExecutorResourceUtils.java#L244
Please either adjust documentation or change implementation to set 1gb by
default
