22.5. zk:set

Abstract

set a znode's data

Synopsis

zk:set [ --help ] [ -i|--import ] { path } { data }

Description

The data stored in a znode should not be too large. ZooKeeper imposes an absolute limit of 1 MB, but in practice a data item should normally be much smaller than that.
Important
To avoid corruption of the Fabric Registry, you should not modify any znodes under the /fabric/ path using the zk:set command. These registry values should only be changed through the fabric console commands—see Chapter 9, Fabric Console Commands.

Arguments
