Subject Re: EC2 remote client woes
Date Thu, 12 Jan 2012 21:24:06 GMT
Yes, it's the same thing, which is why I think the additional
ec2.internal in your hbase-site is suspicious. Let me reiterate:

This works:

echo stat|nc ip-XX-YYY-Z-QQQ.ec2.internal 2181

But this config doesn't:

<value>ip-XX-YYY-Z-QQQ.ec2.internal.ec2.internal</value>

Now what happens if you just use the same one, the one that works?

J-D
