Bitcoin Core 0.15 reindexing blockchain looks like its hanging?
bitcoin-cli getinfo


The getinfo RPC has been removed in the master branch (which is what you are using). Try using a different RPC like getblockchaininfo or getnetworkinfo. The fact that you are getting a response with Method not found indicates that the RPC server is up and running, so the node should be working.

I don't think -daemon and -printtoconsole interact well so you may not actually see the debug lines.
