[QUESTION]: httpclient dependency

[Charles Givre]

Hello all, 
I am doing some work for an Elasticsearch (ES) storage plugin.  I recently 
rebased on the current master and found that broke my plugin due to a 
dependency exclusion.  Basically, the ES modules need the commons-httpclient 
which seems to be excluded by the HBase plugin. My question is can I 
"un-exclude" it or do something in Maven so that the code gets these 
dependencies?
Thanks,
