Harsh J resolved HADOOP-2900.
-----------------------------
Resolution: Not A Problem
This behavior was fixed at some point such that now it is:
[filename]#[symlink-name] and symlinks will always be created with given name -
no secondary configuration is required.
> distributedcache: Can we create symlink without mapred.create.symlink = yes?
> -----------------------------------------------------------------------------

> Key: HADOOP-2900
> URL: https://issues.apache.org/jira/browse/HADOOP-2900
> Project: Hadoop Common
> Issue Type: Improvement
> Components: util
> Reporter: Koji Noguchi
> Priority: Minor
>
> I always thought
> <property>
> <name>mapred.cache.archives</name>
> <value>/archives/arc1.zip#symlink</value>
> </property>
> would create a symlink on the current working directory, but it also requires
> <property>
> <name>mapred.create.symlink</name>
> <value>yes</value>
> </property>
> to be set.
> Can we simplify it so that we always create a symlink whenever there's
> '#wwww' entry?
> Or is 'mapred.create.symlink' necessary since '#' is a valid dfs filename?
