Subject Failed to connect to server
Date Thu, 27 Mar 2014 09:00:18 GMT
Hi,

We have setup Accumulo Instance deployed in cloud. But when I am trying to
connect with it remotely. Using java client, I have this issue:

Have set the client ports to OPEN. Have already checked for missing jars.
Turned vm.swappines to off.
I have already seen this ticket ACCUMULO-687 which has been resolved. But I
am still having this error. Everything is working fine locally on accumulo
instance, I can access accumulo shell. As well as the HTTP monitor on
clients browser.

Your help will be much appreciated. Thank you.

I have used Accumulo 1.5.1, Zookeeper 3.4.5 and Hadoop 2.2.0 for this
environment.
