Not working (Lingual + Hadoop 2.2) Please Help !!

[Hsu Orozco]

Someone please help me to figure out Lingual install problem, thanks

My system information as below:
1. Hadoop2.2 with zookeeper, hbase. All services are perfect.
2. Clustering (two machines): one Master node and one Slave node

I follow the Lingual install command, and everything is fine

> curl http://files.concurrentinc.com/lingual/1.0/lingual-client/install-lingual-client.sh | bash


I use export LINGUAL_PLATFORM=hadoop and export HADOOP_HOME=/opt/hadoop
Then use lingual shell found error, the exception as below:

[root@master bin]# lingual shell
Exception in thread "main" java.lang.NoClassDefFoundError: org/slf4j/LoggerFactory
        at cascading.lingual.shell.Shell.<clinit>(Shell.java:48)

Could not find the main class: cascading.lingual.shell.Shell.  Program will exit.

The problem has stick me couple days, until I found this forum.
I reference Henry Hung's posts and try to setup all variables he mentioned,
and set export LINGUAL_PLATFORM=hadoop2-mr1.

Then problem is still remaining, please see below:
[root@master bin]# lingual shell
ERROR: Unknown platform: hadoop2-mr1

Please someone tell me how to install Cascading Lingual?
