    Hi,

    I am trying to understand the security features in HDP 1.3 and 2.0. Is there any link that provides these details.

    Is there significant difference between HDP 1.3 and 2.0 as far as security is concerned?

    Thanks

    The new feature wrt security in HDP 2.0 is enhanced encryption for data in motion in shuffle, data transfer protocol and jdbc etc. See http://docs.hortonworks.com/HDPDocuments/HDP2/HDP-2.0.6.0/bk_reference/content/reference_chap-wire-encryption.html

    There aren’t any significant differences, HDP 2.0 inherits the same security framework from HDP 1.3.

    As you may know, HDP 2.0 ships YARN and so the daemons that are configured are different from 1.3. JobHistoryServer typically runs as a special user say ‘mapred’ while YARN daemons ResourceManager and NodeManager run as a different ‘yarn’ user. So you may have to set up kerberos principals and keytabs for a different set of users.

    There should be no changes from HDFS point of view.

    Hope that helps.
