Subject Re: connecting Hbase using java
Date Thu, 04 Apr 2013 14:50:39 GMT
yes thank you so much jean, I will switch to eclipse.

now I tried with (java -classpath `~/packages/hbase-0.94.6/bin/hbase
classpath` MyLittleHBaseClient)

code is running but I guess now I have some problem with my hbase and hadoop

I am getting output that you can see at http://paste.ubuntu.com/5676866/
could you please figure out where things are wrong now?
thanks again, your reply are helping me learning basic things.
