Re: hadoop classpath causing an exception (sub-command not defined?)
It looks to me like the change of Nov 21, 2012 added the 'hadoop classpath' call to the accumulo script. ACCUMULO-708 initial implementation of VFS class loader … git-svn-id: https://svn.apache.org/repos/asf/accumulo/trunk@1412398 13f79535-47bb-0310-9956-ffa450edef68 Dave Marion authored 23 days ago Could the classpath sub-command be part of a newer version (0.20.2) of hadoop?

Re: hadoop classpath causing an exception (sub-command not defined?)
Should we add an hadoop version check to the accumulo script? On Fri, Dec 14, 2012 at 7:45 AM, Jason Trost jason.tr...@gmail.com wrote: We saw the same issue recently. We upgraded our dev nodes to hadoop 1.1.1 and it fixed this issue. I'm not sure when class path was added to the hadoop command so a minor upgrade may work too. --Jason sent from my DROID On Dec 14, 2012 7:34 AM, David Medinets david.medin...@gmail.com wrote: It looks to me like the change of Nov 21, 2012 added the 'hadoop classpath' call to the accumulo script.
