Yarn [nodemanager](https://github.com/apache/hadoop/blob/trunk/hadoop-yarn-project/hadoop-yarn/hadoop-yarn-server/hadoop-yarn-server-nodemanager/src/main/java/org/apache/hadoop/yarn/server/nodemanager/containermanager/launcher/ContainerLaunch.java#L1328) exports the environment variables that are inconsistent with the submitted string, the double-quotes are removed after exporting environment variables, so `YarnLocalResourceDescriptor` couldn't parse the string which fetched from System.getenv(). e.g.: ``` $ export _FLINK_DIST_="{"resourceKey":"flink-dist-1.19-SNAPSHOT.jar","path":"hdfs://flink-dist-1.19-SNAPSHOT.jar","size":126733882,"modificationTime":1693301926167,"visibility":"APPLICATION","resourceType":"FILE"}" $ echo $_FLINK_DIST_ {resourceKey:flink-dist-1.19-SNAPSHOT.jar,path:hdfs://flink-dist-1.19-SNAPSHOT.jar,size:126733882,modificationTime:1693301926167,visibility:APPLICATION,resourceType:FILE} ``` I found out Jackson allow to [configure custom quote character](https://github.com/FasterXML/jackson-core/issues/549) to serialize Object, for example: single-quote, later I'll figure out the exactly way to serialize the string. -- This is an automated message from the Apache Git Service.
