alluxio.cli.fsadmin.pathconf.ShowCommand

All Implemented Interfaces:

Command, java.io.Closeable, java.lang.AutoCloseable

public final class ShowCommand
extends AbstractFsAdminCommand

Show path level configurations.

It has two modes: 1. without option "--all", only show configurations for the specific path; 2. with option "--all", show all configurations applicable to the path.

For example, suppose there are two path level configurations: /a: property1=value1 /a/b: property2=value2 Then in mode 1, only property2=value2 will be shown for /a/b, but in mode 2, since /a is the prefix of /a/b, both properties will be shown for /a/b.
