shell extensions
As part of development for GeoMesa, I've found it valuable to have
maintenance and other custom operations available at the accumulo shell.
To support this, I have modified the Shell class to load commands defined
as SPI META-INF/services in jars in $ACCUMULO_HOME/lib/ext. This allows
developers to create a jar with a file:
META-INF/services/org.apache.accumulo.core.util.shell.Command
which contains one Command per line such as:
geomesa.core.util.shell.ListFeaturesCommand
geomesa.core.util.shell.InitializeFeatureCommand
geomesa.core.util.shell.IngestFeatureCommand
geomesa.core.util.shell.OptimizeIndexCommand
geomesa.core.util.shell.RefreshBoundsCommand
I have put up a branch of the modification here:
https://github.com/ccri/accumulo/tree/extensible_shell
The actual code change is quite minimal but I had to pull the abstract
Command class up into its own file so I could use the ServiceLoader to load
Command resources.
Does this sound like something that could be valuable to others?
Thanks,
Anthony

No, we don't add new features in minor releases

Welp, it's almost exactly the same, except for the scripting part. Guess
this won't make it into 1.5.1?

Anthony,
I have not had a chance to look at your code yet, but it sounds similar to
the feature described in https://issues.apache.org/jira/browse/ACCUMULO-1399
What are your thoughts?
Mike
