Jason Lowe commented on YARN-2377:
----------------------------------
Thanks for the patch, Gera. I think the toString should be on
SerializedException rather than SerializedExceptionPBImpl, since there's
nothing implementation-specific about the way it tries to convert to a string
-- it always goes through the interfaces to get the necessary things. If a
specific implementation really needs a different toString method then they can
always override.
Nit: sringify should be stringify. Also curious why it isn't static or
otherwise assumes e == this and not take the additional parameter, since we can
delegate to cause.stringify when processing the cause portion of the traceback.
