Arpit Gupta updated HDFS-3978:
------------------------------
Description:
We should create a new site document to explicitly list down the know
incompatible changes between hadoop 1.x and 2.x
This will make it easier for users to determine these differenence
was:
The following incompatible changes were noticed between branch-1 and branch-2
caused by HADOOP-8551
1. mkdir would create parent directories in branch-1 if they did not exist. In
branch-2 users have to explicitly send mkdir -p
2. Create a multi level dir in branch 1 something like
mkdir /test/1
/test would get permissions 755 and /test/1 would get the permissions based on
your umask settings
however if you run the command in branch-2
mkdir -p /test/1
both /test and /test/1 will get the permissions based on your umask.
These are significant changes that we should document.
