Subject remote accumulo instance issue
Date Wed, 08 May 2013 15:09:51 GMT
I have seen this as ticket ACCUMULO-687 which has been marked resolved, but
I still see this issue.

I am connecting to a remote accumulo instance to query and to launch
mapreduce jobs using AccumuloRowInputFormat, and I'm seeing an error like:

91 [main-SendThread(padres.home:2181)] INFO org.apache.zookeeper.ClientCnxn
 - Socket connection established to padres.home/,
initiating session
166 [main-SendThread(padres.home:2181)] INFO
org.apache.zookeeper.ClientCnxn  - Session establishment complete on server
padres.home/, sessionid = 0x13e7b48f9d17af7, negotiated
timeout = 30000
1889 [main] WARN org.apache.accumulo.core.client.impl.ServerClient  -
Failed to find an available server in the list of servers:
[ (120000), (120000), (120000), (120000), (120000), (120000), (120000), (120000)]

My zookeeper's "tservers" key looks like:
[zk: localhost:2181(CONNECTED) 1] ls

My masters and slaves file look like:
[hadoop@padres conf]$ cat masters
[hadoop@padres conf]$ cat slaves

tracers, gc, and monitor are the same as masters.

I have no issues executing on the master, but I would like to work from a
remote host. The remote host is on a VPN, and its default resolver is NOT
the resolver from the remote network. If I do reverse lookup over the VPN
*using* the remote resolver it shows proper hostnames.

My concern is that something is causing the "host:port" entry plus the port
to come up with this concatenated view of host:port:port, which is
obviously not going to work.

What else can I try? I previously had hostnames in the masters/slaves/etc.
files but now have the IPs. Should I re-init the instance to see if it
changes anything in zookeeper?
