Re: ISpark class not found
Sounds like ipython notebook issue, not an ISpark one. Might want to reinstall pip install ipython[notebook], which will grab the notebook necessary components like tornado. Try spinning up ispark console instead of notebook to see if the ISpark kernel is functioning. ipython console —profile spark From: MEETHU MATHEW meethu2...@yahoo.co.inmailto:meethu2...@yahoo.co.in Reply-To: MEETHU MATHEW meethu2...@yahoo.co.inmailto:meethu2...@yahoo.co.in Date: Wednesday, November 12, 2014 at 2:26 AM To: Capital One benjamin.la...@capitalone.commailto:benjamin.la...@capitalone.com, user@spark.apache.orgmailto:user@spark.apache.org user@spark.apache.orgmailto:user@spark.apache.org Subject: Re: ISpark class not found Hi, I was also trying Ispark..But I couldnt even start the notebook..I am getting the following error.
