For files that have a Cloudera copyright (and no other copyright notice), make changes to follow the ASF source file header policy here: http://www.apache.org/legal/src-headers.html#headers Specifically: 1) Remove the Cloudera copyright. 2) Modify NOTICE.txt according to http://www.apache.org/legal/src-headers.html#notice to follow that format and add a line for Cloudera. 3) Replace or add the existing ASF license text with the one given on the website. Much of this change was automatically generated via: git grep -li 'Copyright.*Cloudera' > modified_files.txt cat modified_files.txt | xargs perl -n -i -e 'print unless m#Copyright.*Cloudera#i;' cat modified_files_txt | xargs fix_apache_license.py [1] Some manual fixups were performed following those steps, especially when license text was completely missing from the file. [1] https://gist.github.com/anonymous/ff71292094362fc5c594 with minor modification to ORIG_LICENSE to match Impala's license text.
