Yang Wang commented on FLINK-15053:
-----------------------------------
[~xintongsong] Thanks for creating this ticket. I think it just because we have
introduced many updated configs from 1.10. These configs may contains some
characters need to be escaped. FLINK-13184 uses dynamic properties instead of
always uploading a taskmanage-conf.yam file to dfs.
For the solution, i think we always use single quotes for the values. If the
value contains single quote, it needs to be escaped. For example, `{{-D
taskmanager.memory.managed.size='1234 bytes' -D key1='value\'xxxx\'yyyy'`.}}
> Configurations with values contains space may cause TM failures on Yarn

> URL: https://issues.apache.org/jira/browse/FLINK-15053
> Project: Flink
> Issue Type: Bug
> Components: Deployment / YARN, Runtime / Coordination
> Affects Versions: 1.10.0
> Reporter: Xintong Song
> Priority: Major
> Fix For: 1.10.0
>
>
> Currently on Yarn setups, we are passing task executor specific
> configurations through dynamic properties in the starting command (see
> FLINK-13184).
> If the value of configuration contains space, the dynamic properties may not
> be correctly parsed, which could cause task executor failures. On occurrence
> can be found in FLINK-15047.
> It would be good to allow spaces when passing dynamic properties. E.g.,
> surrounding the values with double quotation marks, or escaping special
> characters.
