Subject [GitHub] incubator-storm pull request: STORM-346: added AutoHDFS class that...
Date Fri, 18 Jul 2014 19:24:18 GMT
Github user Parth-Brahmbhatt commented on the pull request:
    The simplest alternative seems to be no implementation for IAutoCredentials needed for
AutoHDFS to work. In other words users will not  have to specify any class for ""
config for auto hdfs to work.
    User will specify as "nimbus.credential.renewers.classes" and AutoHDFS will
only implement ICredentialsRenewer. In the prepare phase of, which should be
called on nimbus startup, we can get the HDFS credentials.
    I have one clarifying question. The ICredentialsRenewer implementations seems to be loaded
by reading "nimbus.credential.renewers.classes" config at startup by nimbus. If I understand
correctly this means if we use ICredentialsRenewer the users who have a running nimbus and
wants to use AutoHDFS will have to change the config and restart the nimbus. Is that acceptable?
