Hi, The ! at the beginning of the hadoop.profile property in hadoop-1.0 profile indicates that if the hadoop.profile property is not specified or absent, then the profile will be activated. So if you didn't specify it as a system property (e.g. -Dhadoop.profile=XXXX), it would be used by default.
Given what I explained above, for your second question, you need to specify -Dhadoop.profile=2 and just omit -Phadoop-2 to activate the hadoop-2 profile in your build.
