Mona Chitnis commented on OOZIE-615:
------------------------------------
One more observation from testing on my side. When trying to stream logs for
server A's job from server B, it is having problems in the HttpConnection
In ZKXLogStreamingService method fetchOtherLog()
{code}
if ((conn.getResponseCode() == HttpURLConnection.HTTP_OK)) {
{code}
This is returning false with error state - "This request requires HTTP
authentication". In browser, I confirmed that the WS URL constructed is
correct, and gives the logs as expected after a page refresh. Via back end
here, it looks like we need to perform http auth again.

> As Oozie becomes a critical component in the Hadoop ecosystem users needs
> assured availability of the services provided by Oozie. To support this need
> Oozie should include a new feature to support high availability. This
> feature needs to take into consideration that Oozie provides RESTful APIs,
> Java APIs, and a command line API that should all be insensitive to the
> availability of any specific server or components. At Yahoo! it is not
> required that there be session fail-over from the client. It is acceptable
> for the client to reconnect if a session is lost as long as the state data
> managed by the Oozie service is not lost.
