Hiii alll,
I decided to share with you my problem, because my professor and colleagues 
were not able to solve it.
First I will tell u my configurations : I made a client and sever for hadoop. 
The server is on ubuntu cloudera 3 update 3 (chd3u3). My client is on my Mac 
OXs.
Second, I used a code for hbase thrift api (democlient.java) in client, the 
hbase folder I downloaded it from cloudera same release (chd3u3).
The problem is when running the program, if I decided to create table or delete 
table or use any function related to tables, I enter an infinite loop, the 
client is waiting for the server to respond but the server is not replying to 
requests.
As for the connectivity, I checked that everything is OK, I am sure of thrift 
server port (9090) and the server is running. Also by checking I found that 
server and client are connected and seen each others. But as for handling the 
requests, the server is unable to do so. 
Here is link for cloudera

So any help ?? 
Best Regards,Dalia Sobhy
