Subject Re: Problem compiling from source

Hi Harold,
  It seems you don't have latest hdfs code. KerberosInfo annotation has
slightly changed in the latest code.
  Also, KerberosInfo not being found means you have older jar for common.
Try 'ant clean clean-cache'  before compiling.

To use your on version of jar do ant mvn-install in the the common
And in hdfs give -Dresolvers=internal flag to the ant command line. Please
make sure to clean-cache before this.
