I am attempting to build Spark 1.6.0 from source on EL 6.3, using Oracle jdk 1.8.0.45, Python 2.7.6, and Scala 2.10.3. When I try to issue build/mvn/ -DskipTests clean package, I get the following:
[INFO] Using zinc server for incremental compilation [info] Compiling 3 Java sources to /misc/local/spark-versions/spark-1.6.0-patched/spark-1.6.0/tags/target/scala-2.10/classes... [error] javac: invalid source release: 1.7 [error] Usage: javac <options> <source files> [error] use -help for a list of possible options [error] Compile failed at Jan 28, 2016 8:56:36 AM [0.113s] I tried changing the pom.xml to have java version as 1.8, but I just got the same error with invalid source release: 1.8 instead of 1.7. My java -version and javac -version are reporting as 1.8.0.45, and I have the JAVA_HOME env set. Anyone have any ideas? Incidentally, building 2.0.0 from source worked fine… Thanks, Ken
