The ZooKeeper server continually saves znode snapshot files and, optionally, transactional logs in a Data Directory to enable you to recover data. It's a good idea to back up the ZooKeeper Data Directory periodically. Although ZooKeeper is highly reliable because a persistent copy is replicated on each server, recovering from backups may be necessary if a catastrophic failure or user error occurs. When you use the default configuration, the ZooKeeper server does not remove the snapshots and log files, so they will accumulate over time. You will need to clean up this directory occasionally, taking into account on your backup schedules and processes. To automate the cleanup, a zkCleanup.sh script is provided in the bin directory of thezookeeper base package. Modify this script as necessary for your situation. In general, you want to run this as a cron task based on your backup schedule. The data directory is specified by the dataDir parameter in the ZooKeeper configuration file, and the data log directory is specified by the dataLogDir parameter. ... View more

Thanks to everyone for the suggestions. I wanted to give an update as I am able to connect to the prompt, hopefully will help others who have similar environments similar to mine. My challenge was to get the SSH working from Windows 10 (Surface Pro) where the VM was created in Azure (classic) General guidelines https://azure.microsoft.com/en-us/documentation/articles/virtual-machines-windows-use-ssh-key/ Installed GitHub with GitShell. Ran the command from GitShell to generate the key file and .pem file (openssl.exe req -x509 -nodes -days 365 -newkey rsa:2048 -keyout myPrivateKey.key -out myCert.pem) Installed PuttyGen Convert to .rsa file so PuttyGen can understand (openssl rsa -in ./myPrivateKey.key -out myPrivateKey_rsa# chmod 600 ./myPrivateKey_rsa) Load the private key via PuttyGen, save the PrivateKey as .ppk file Next copy the PublicKey from PuttyGen. Now, I attempted to take the key to existing Azure VM, Settings, Reset Password and change to SSH Public Key. Although, the key was accepted, it did not finish for a long time. The restart did not help. Kept getting Server key was refused. So, I created a new VM using Marketplace Sandbox using Resource Manager (not classic) using the Public Key. Note down the user name! Ran Putty, provided the IP address using port 22, on SSH -> Auth page, provided the .ppk file saved earlier from PuttyGen. When prompted, provide the username used in Azure portal. Voila! ...
