Subject ZooKeeper available but no active master location found
Date Wed, 09 Apr 2014 16:58:02 GMT
Hi

I downloaded and installed hortonworks sandbox 2.0 for virtualbox.
HBase version is: 0.96.0.2.0.6.0-76-hadoop2, 
re6d7a56f72914d01e55c0478d74e5cfd3778f231
[hbase@sandbox twitbase-master]$ cat /etc/hosts
# Do not remove the following line, or various programs
# that require network functionality will fail.

10.0.2.15       sandbox.hortonworks.com sandbox

[hbase@sandbox twitbase-master]$ hostname
sandbox.hortonworks.com

[root@sandbox ~]# netstat -lnp | grep 2181

So far is good.

I'd like to play with a code: https://github.com/hbaseinaction/twitbase

downloaded and made package: mvn package and  got twitbase-1.0.0.jar.

When I try to exec code I will get:

The line that drops error is: HBaseAdminadmin=newHBaseAdmin(conf);

Log line: "ZooKeeper available but no active master location found" is 
from org/apache/hadoop/hbase/client/HConnectionManager.java

As much I read ther might be somthing wrong with binding and DNS resolving.

Any hints?
