Server management limitations

Here are some of the server management guidelines that you should consider before implementing Kudu.

Production deployments should configure a least 4 GiB of memory for tablet servers, and ideally more than 16 GiB when approaching the data and tablet scale limits.
Write ahead logs (WALs) can only be stored on one disk.
Data directories cannot be removed. You must reformat the data directories to remove them.
Tablet servers cannot change their address or port.
Kudu has a hard requirement on having an up-to-date NTP. Kudu masters and tablet servers will crash when out of sync.
