Yang Wang commented on FLINK-15053:
-----------------------------------
All the value of dynamic properties will be put into a pair of single quotes.
If the value contains single quote, will be replaced with <SINGLE_QUOTE>. When
loading the dynamic properties, it will be restored to single quote. I do not
suggest to use \' to escape, since it will not work for start command of bash.
{code:java}
// start command
bash -c "$JAVA_HOME/bin/java -Xmx424m ... ...
org.apache.flink.yarn.entrypoint.YarnJobClusterEntrypoint -Dkey1='\'value'
-Dkey2='20 s' -Dkey3='value3'"
bash -c "$JAVA_HOME/bin/java -Xmx424m ... ...
org.apache.flink.yarn.entrypoint.YarnJobClusterEntrypoint
-Dkey1='<SINGLE_QUOTE>value' -Dkey2='20 s' -Dkey3='value3'"{code}

> Key: FLINK-15053
> 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.
