It all seems to be related to those two first lines:
[ERROR] [g.openhab.io.net.http.HttpUtil] - Fatal transport error: java.net.SocketTimeoutException: Read timed out
[ERROR] [.o.b.http.internal.HttpBinding] - No response received from 'http://weather.yahooapis.com/forecastrss?w=638242&u=c'
The two sets of errors are not related. the rrd4j errors indicate that you need to create the /opt/openhab/etc/rrd4j folder.
The first error means the Yahoo website did not respond to your query for information. This could be a problem in OH or it could be a problem with yahoo. I don’t know.
But since you are now just starting I highly recommend using OH 2. If you are worried about it being in beta, realize that the official release is early next week.
