How to grep output of ls -lhR / for particular owner (ex. root)?

Question

I am a zookeeper newbie. I have three nodes in three separate data centers. I will need to read and write data from the python pykeeper API? So...

1) which node to I read and write from? Does it matter? Round robin? Write to master, read from slaves?

2) How do I know wich server was elected as master? Do I care? That I have yet to figure out.

3) For now I am using the following to connect to zookeeper.

import zc.zk
from random import choice
zk_servers = ['111.111.111.111:2181','111.111.111.222:2181','111.111.111.333:2181']
zk = zc.zk.ZooKeeper(choice(zk_servers))

This begs the question, what if a zk node fails? Should I place nodes behind HA proxy to load-balance the requests?

Any advice for using best practice for reading and writing to zk nodes is mush appreciated.

Thanks

Solution

find should answer:

sudo find / -user root

To search a specific directory, just replace / with the full path. You can drop the sudo part of the command if you don't mind warnings about being unable to read special files.

For group ownership finds, use:

sudo find / -group root

you should probably start by reading the docs, zookeeper.apache.org/doc/r3.4.3/zookeeperOver.html

I was going to suggest some hackery using cut and grep, but this is much cleaner.

This comment isn't true. The same data resides on all nodes. It doesn't matter which data you request. As such, Zookeeper does not scale horizontally with respect to data. It does, however, scale horizontally in terms of reads.
