HQ plugin doesn't work for ES2.3.3

[mannoj...@phonepe.com]

I see that HQ(2x or 1x)  doesn't work for ES 2.3.3 . 

I install HQ and start Elastic search it won't work.

If I start ES and then install, and then if I restart ES. ES won't start.

My command I execute to get HQ is 

/usr/share/elasticsearch/bin/plugin install royrusso/elasticsearch-hq/v2.3.3.

or 

/usr/share/elasticsearch/bin/plugin install royrusso/elasticsearch-hq/v2.0.0

or 

/usr/share/elasticsearch/bin/plugin install royrusso/elasticsearch-hq/v1.0.0

It points to https://github.com/royrusso/elasticsearch-hq/archive/master.zip and also in other branches I see /usr/share/elasticsearch/plugins/hq/plugin-descriptor.properties has version=1.0.0. Not sure if this is the issue. Not sure how we can fix it. 

All the cases I get below error.

java.lang.IllegalStateException: Could not load plugin descriptor for existing plugin [hq]. Was the plugin built before 2.0?

FIXED IT BY DOING AFTER INSTALLING

chown -R elasticsearch:elasticsearch /usr/share/elasticsearch/plugins

And then service elasticsearch start (Worked).
