All,
Just a reminder that we have the Rya working group tomorrow.  This week we
will be going over potential methods of improving client configuration of
Rya through a centralized administration mechanism.  I'm not going to set
up a webex, but we can use the following line for tomorrow's discussion:
Call-in toll-free number: 1-888-5981409

I'll send out slides tomorrow before the working group!
Thanks,

Hi Amila,

1) Rya should be able to use whatever Accumulo instance name you provide -
did you try to use Rya with a given Accumulo instance name and it did not
work? What did you try?

2)

DId you look at the vagrant script to see if it does something different
than you did?

DId you have the problem first time you installed Accumulo, or only on
restart?

Did you try to ping Zookeeper, to make sure it is up?
Ping Zookeeper (run: echo ruok | nc 127.0.0.1 2181). -- or whatever ip/port
you use for Zookeeper

   - If Zookeeper is okay, you should see the response imok
   - Otherwise, restart Zookeeper (run something similar to
~/Installs//zookeeper-3.4.5-cdh4.5.0/bin/zkServer.sh
   start)


3) Try to connect to the Rya "office hours" tomorrow (Wednesday) at 12pm
EST. A message with connect information should be sent out tomorrow
morning. Then maybe you will be able to share your screen and ask for help.

Adina
