Druid spec file parse exception in windows

I have druid configured to run on windows. However, when I start druid, I get an exception by the Jackson parser while trying to run the Wikipedia example. The exception is:

2015-08-31T19:54:16,074 INFO [main] io.druid.guice.JsonConfigurator - Unable to parse [druid.realtime.specFile]=[C:\applications\druid-0.8.0\examples\wikipedia\wikipedia_realtime.spec] as a json object, using as is.
com.fasterxml.jackson.core.JsonParseException: Unrecognized character escape ‘a’ (code 97)
at [Source: “C:\applications\druid-0.8.0\examples\wikipedia\wikipedia_realtime.spec”; line: 1, column: 6]
at com.fasterxml.jackson.core.JsonParser._constructError(JsonParser.java:1419) ~[jackson-core-2.4.4.jar:2.4.4]

I have checked the Wikipedia spec file and there are no hidden characters and it can be parsed by other tools. Can someone see if I am doing anything wrong?


I don’t know anyone who have been able to successfully deploy druid on windows. I would highly recommend using a unixy machine.
