如何在Java中检索唯一的Spark作业ID？

Question

I've already seen this post . But I don't seem to be able to find applicationid on JavaSparkContext .

Actually want I need is a unique id that identifies the application. I could just generate uuid and set it as app-name. Is there a better way?

Try this :-

JavaSC.env().conf().getAppId(); 

or

ctxt.getConf().getAppId()
