• Type: Improvement
• Status: Resolved

• Fix Version/s: 1.3.0
• Labels: newbie
• Target Version/s: 1.3.0
• Hadoop Flags: Reviewed
• Release Note: FsShell mkdir now accepts a -p flag. Like unix, mkdir -p will not fail if the directory already exists. Unlike unix, intermediate directories are always created, regardless of the flag, to avoid incompatibilities.

Description

Per HADOOP-8551 let's port the mkdir -p option to branch-1 for a 1.x release to help users transition to the new shell behavior. In Hadoop 2.x mkdir currently requires the -p option to create parent directories but a program that specifies it won't work on 1.x since it doesn't support this option.
