Subject Storm failover, is it possible to know the last succeeded bolt when fail method gets called in spout?
Date Wed, 28 May 2014 00:58:02 GMT
Hi guys,

For a Storm topology, if a tuple failed to be processed (either timed out
or fail method got called on the tuple explicitly), I understand that fail
method of the spout will be called with the tuple message id. Other than
that, can Storm provide any info as to the last bolt that had processed the
tuple successfully? Thanks in advance!
