Celeborn CLI

Celeborn CLI is the command line interface of Celeborn including the management of the master and worker service etc.

Note

: CLI requires version 0.6+ of Celeborn to work since it depends on OpenAPI for API calls.

Availability

Version	Available in src tarball?	Available in bin tarball?
< 0.6.0	No	No
>= 0.6.0	Yes	Yes

Setup

To get the binary package apache-celeborn-<VERSION>-bin.tgz, download the pre-built binary tarball from Download or the source tarball from Download for building Celeborn according to Build.

After getting the binary package apache-celeborn-<VERSION>-bin.tgz:

$ tar -C <DST_DIR> -zxvf apache-celeborn-<VERSION>-bin.tgz
$ ln -s <DST_DIR>/apache-celeborn-<VERSION>-bin <DST_DIR>/celeborn

Export the following environment variable and add the bin directory to the $PATH:

$ export CELEBORN_HOME=<DST_DIR>/celeborn
$ export PATH=${CELEBORN_HOME}/sbin:$PATH

You can use the following command to verify whether CLI works well:

$ celeborn-cli -V
Celeborn CLI - Celeborn <VERSION>
