Subversion river and elastic search compatability

Hi

I want to use this elastic search plugin.

When i tried to install this plugin with the latest version of Elastic search the plugin failed with
./plugin install file:/root/SubversionRiver-master.zip
-> Installing from file:/root/SubversionRiver-master.zip...
Trying file:/root/SubversionRiver-master.zip ...
Downloading .DONE
Verifying file:/root/SubversionRiver-master.zip checksums if available ...
NOTE: Unable to verify checksum for downloaded plugin (unable to find .sha1 or .md5 file to verify)
ERROR: Could not find plugin descriptor 'plugin-descriptor.properties' in plugin zip

Since there is no properties file available.
What version of elastic search is compatible with this plugin ?

ES 2.X and above will not work with rivers.

You will need to ask the author about the compatibility before that.

Hi Mark

Thanks appreciate your reply.
Guess the author is not obligated to respond to me as its a open source software.
