------------------------------------------
Andrew, I'm not that familiar with co-processor in HBase. Could you please
elaborate on what kind of files are you expecting to be dropped into
/etc/hbase/modules.d?
Basically, if you could walk us through a scenario of using this proposed
feature -- that would be greatly appreciated!
> Introduce a modules system for HBase coprocessor applications
> -------------------------------------------------------------

> Key: BIGTOP-1007
> URL: https://issues.apache.org/jira/browse/BIGTOP-1007
> Project: Bigtop
> Issue Type: Improvement
> Affects Versions: 0.7.0
> Reporter: Andrew Purtell
> Assignee: Andrew Purtell
>
> Consider a modules system convention ("/etc/hbase/modules.d"), a common
> pattern used for example by Apache httpd, for easily installation and removal
> of HBase coprocessor applications.
> Within the modules.d/ directory, one additional level of subdirectories can
> be created, into which a package can drop site xml fragments and scripts to
> execute after regionserver and master (re)start. Future packages that ship an
> HBase coprocessor application could then add configuration bits without
> concern about collisions and trigger a regionserver reload in postinstall.
> HBase already ships a tool for merging configuration files. Changes required
> for this will be proposed upstream if needed.
