Re: [geomesa-users] Exception in thread "main" java.lang.NoClassDefFound

[Jim Hughes <jnh5y@xxxxxxxx>]

Paul,

A +1 to Jeff's suggestion.  There's also the 'geomesa classpath' command 
which will show the jars which are on the classpath.  If you don't see 
something like /opt/hadoop/share/hadoop/common/hadoop-common-2.2.0.jar, 
that'd be the problem.

Cheers,

Jim
