To have a RegionServer test a set of codecs and fail-to-start if any
code is missing or misinstalled, add the configuration
hbase-site.xml with a value of
codecs to test on startup. For example if the
lzo,gz and if lzo is not present
or improperly installed, the misconfigured RegionServer will fail
Administrators might make use of this facility to guard against the case where a new server is added to cluster but the cluster requires install of a particular coded.
