Subject [jira] [Updated] (HADOOP-11485) Pluggable shell integration
Date Thu, 15 Jan 2015 21:44:34 GMT

     [ https://issues.apache.org/jira/browse/HADOOP-11485?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Allen Wittenauer updated HADOOP-11485:
--------------------------------------
    Attachment: HADOOP-11485-00.patch

-00:
* First pass at this functionality to get a sense if this is the right approach
* yarn, hdfs, and mapred classpath and yarn finalizer moved to frag files
* KNOWN BUG: hdfs-fragment doesn't get moved into libexec/shellfrags as part of the distribution
(grumble grumble maven grumble grumble)
* KNOWN BUG: missing license info at the top
* Stripped ending line spaces

A few notes:
* YARN properties are now instantiated on every java command line.
* This doesn't deprecate anything, as that should be handled in that other jira.

> It would be useful to provide a way for core and non-core Hadoop components to plug into
the shell infrastructure.  This would allow us to pull the HDFS, MapReduce, and YARN shell
functions out of hadoop-functions.sh.  Additionally, it should let 3rd parties such as HBase
influence things like classpaths at runtime.
