Subject Re: httpclient conflict in spark
Date Thu, 30 Mar 2017 17:59:10 GMT
Hi Steve,

I was indeed using spark 2.1. I was getting this error while calling spark
via Zeppelin. Zeppelin comes with older version of httpclient apparently. I
copied the httpclient 4.5.2 and httpclient 4.2.2 into
zeppelin/interpreter/spark and this problem went away.


Thank you for your help.
