Accumulo Config Question
All,
Is anybody using ZK to configure Accumulo?
Heretofore, I've been focused on Accumulo and Zookeeper was just a means to
that end. Lately, I dug a bit into ZK and learned one of it's purposes is
to provide a common point of configuration. But in the Accumulo
documentation, I've seen nothing about using ZK in that way. Is anybody
using ZK to configure Accumulo? e.g. speccing the slaves list in ZK as
opposed to the conf directory.
Thanks

People tend to make configuration changes by zookeeper first, and then
migrate them to the config files for CM/documentation purposes.
We could get the config files from HDFS, but that's not supported right
now. Accumulo 1.6 can get jar files from there, for the reason you state:
it simplifies deploying the correct file to all nodes in the cluster.

I cited the slaves file as no more than a possibility, hence the e.g.
I remember, when I ran a Hadoop cluster, using rsync to deploy config
updates to all nodes. I assumed I would be doing the same with Accumulo
once I got into multi nodes. Apparently, from what you're telling, me
this copying remains the preferred practice despite what ZK offers.
Interesting.

I don't know of anyone putting the slaves file in zookeeper. However,
nearly all the basic settings can be configured in zookeeper: changing any
setting in the shell puts the configuration change in zookeeper.
That said, most people like to get their changes in the conf directory
because those files can be managed easily with CM tools and install tools.
