Subject Re: Unable to see completed application in Spark 2 history web UI
Date Wed, 15 Aug 2018 14:25:53 GMT
Thanks Manu, Do you know how i can see which user the UI is running,
because i'm using cloudera manager and i created a user for cloudera
manager and called it spark but this didn't solve me issue and here i'm
trying to find out the user for the spark hisotry UI.
