java - Error while submitting a job with Hadoop 2.6.0 on Windows -

i'm working on java project running hadoop 0.20.1 , i'm trying migrate hadoop 2.6.0. once i've changed corresponding hadoop jar files in project, obtain following error when submitting job:

i've read problem related hadoop binaries, i've built them myself, placed them in "c:\hadoop\bin" , environment variable hadoop_home has right value.

i'm running project on eclipse, on machine windows 7 64 bits , java 8.

can me this?

thanks!

i've solved problem. had java 8 32 bits installed instead of 64 bits version. installed right version , hadoop jobs submitted perfectly.
