    Ari Rabkin commented on HADOOP-5308:
    ------------------------------------

    Not quite sure I understand what this patch does. What's the benefit of introducing this new isRunning variable that's never set? Why do we both log exceptions, and print the stack trace to stderr? This seems redundant.

    Probably at some point we should have a policy about when to use printStackTrace().

    Jerome Boulon commented on HADOOP-5308:
    ---------------------------------------

    If an adaptor throws any exception the tailer will exit from the while loop and therefore will stop producing new chunks.
    This patch add a try/catch inside the loop to avoid this problem.
