I created a slave, and I am trying to connect it.
This is a brand new installation.

Here is the info on the slave:
------
[root@jenkins-slave1 ~]# uname -a
Linux jenkins-slave1.[REDACTED].com 2.6.32-431.el6.x86_64 #1 SMP Fri Nov 22 03:15:09 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux
[root@jenkins-slave1 ~]# /usr/bin/java -version
java version "1.6.0_30"
OpenJDK Runtime Environment (IcedTea6 1.13.1) (rhel-3.1.13.1.el6_5-x86_64)
OpenJDK 64-Bit Server VM (build 23.25-b01, mixed mode)
------

however when trying to connect the node it cannot find java:
