Normally, if you have downloaded Spark from ignite-realtime website for Linux, on tar.gz format, after you extract it, and run with sh command, it will be run. But when you use 64 bit Linux OS, it wont run, and show this error :

Preparing JRE …
./Spark: bin/unpack200: /lib/ bad ELF interpreter: No such file or directory
Error unpacking jar files. Aborting.
You might need administrative priviledges for this operation.

To solve this problem, remove the “jre” folder in the extracted directory of Spak.tar.gz file.  Then re run the spark using sh command. It’s Work !!!
