[jira] [Commented] (FLINK-9787) Change ExecutionConfig#getGlobalJobParameters to return an instance of GlobalJobParameters instead of null if no custom globalJobParameters are set yet

    [ https://issues.apache.org/jira/browse/FLINK-9787?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16812145#comment-16812145 ] 

LiuJi commented on FLINK-9787:
------------------------------

Agree, it's a good idea to avoid NPE when invoke getGlobalJobParameters.toMap(). Is there anyone work on this issue？

> Currently when accessing ExecutionConfig#getGlobalJobParameters this will return `null` if no globalJobParameters are set. This can easily lead to NullPointerExceptions when used with getGlobalJobParameters.toMap()
> An easy improvement for this would be to just return a new instance of GlobalJobParameters if none is set with the empty map as the parameters
> This would be a breaking change since we expose this via RuntimeContext#getExecutionConfig
