Yes, the idea is almost the same -- LLAP daemons can accept tasks from
different Tez AMs, whereas MR3 containers can accept tasks from different
DAGs. A minor difference is that in the case of MR3, a single shared AM can
manage multiple concurrent DAGs. As a result, there is no need to start a
new
It would be interesting to see how this compares to Hive LLAP on Tez. Since
the llap daemons contain a queue of tasks that is shared amongst many Tez
AMs, it could have similar characteristics to the way MR3 is sharing the
containers between the AMs.
