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.
