Subject Re: Unable to see completed application in Spark 2 history web UI
Date Thu, 16 Aug 2018 07:05:19 GMT

I'm using cloudera manager with single user mode and every process is
running with cloudera-scm user, the cloudera-scm is a super user and this
is why i was confused how it worked in spark 1.6 and not in spark 2.3
