--------------------------------------
Summary: Introduce a modules system for HBase coprocessor
applications
Key: BIGTOP-1007
URL: https://issues.apache.org/jira/browse/BIGTOP-1007
Project: Bigtop
Issue Type: Bug
Affects Versions: 0.7.0
Reporter: 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.
