Red Hat Summitzk:set
Name
zk:set — 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 8, Fabric Console Commands.
Arguments
Table 17.5, “zk:set Arguments” describes the commands arguments.
