Install Spark and Hadoop in the same machine I'm trying to install Spark Apache and Hadoop in the same machine. Spark will be used to process data, and HDFS from Hadoop will be used to store data. I first started by installing spark and it worked perfectly. But, when I started installing Hadoop and set the JAVA_HOME environment variable HDFS worked, but spark break down and shows: Files was unexpected at this time. when I launched it. When I deleted JAVA_HOME, Spark worked again but it's not the case for HDFS. What should I do in this case?
The Hadoop stack is difficult to setup and people complain that you can't trust any answers to problems over 6-12 months old. I would recommend getting a pre-configured Hadoop/Spark setup from Cloudera or HortonWorks. Both have free community editions.
