Description

The REST server is successfully started,  when I send a http request to the server,  it response "Unavailable" result.Then I check the log file, there is no obviously error or warning infomation, I must to debug the code to find out the real cause of it. Actually, it was caused by hbase client connection .

I think it is neccessary to record the class RESTServlet.java getAdmin() and getTable()  IOException to log file, it can make finding problems becomes simple.
