Hi, I would like to add below points : 1) Ignite YARN is started once [Server] and it will not be stopped between iterations. This means that only once the Ignite nodes are negotiated between YARN and Ignite. Once finalized this should be the same.
Please find below the server logs. [12:30:46] Topology snapshot [ver=1, servers=1, clients=0, CPUs=48, heap=9.9GB] [12:30:46] Topology snapshot [ver=2, servers=2, clients=0, CPUs=96, heap=20.0GB] [12:30:47] Topology snapshot [ver=3, servers=3, clients=0, CPUs=144, heap=30.0GB] [12:30:47] Topology snapshot [ver=4, servers=4, clients=0, CPUs=192, heap=39.0GB] [12:30:47] Topology snapshot [ver=5, servers=5, clients=0, CPUs=240, heap=49.0GB] [12:30:47] Topology snapshot [ver=6, servers=6, clients=0, CPUs=240, heap=59.0GB] [12:30:47] Topology snapshot [ver=7, servers=7, clients=0, CPUs=240, heap=69.0GB] [12:30:48] Topology snapshot [ver=8, servers=8, clients=0, CPUs=240, heap=79.0GB] [12:30:48] Topology snapshot [ver=9, servers=9, clients=0, CPUs=240, heap=89.0GB] [12:30:48] Topology snapshot [ver=10, servers=10, clients=0, CPUs=240, heap=99.0GB] [12:50:26] Topology snapshot [ver=11, servers=10, clients=1, CPUs=240, heap=120.0GB] [12:54:18] Topology snapshot [ver=12, servers=10, clients=0, CPUs=240, heap=99.0GB] [12:56:07] Topology snapshot [ver=13, servers=10, clients=1, CPUs=240, heap=120.0GB] [13:00:49] Topology snapshot [ver=14, servers=10, clients=0, CPUs=240, heap=99.0GB] [13:06:28] Topology snapshot [ver=15, servers=10, clients=1, CPUs=240, heap=120.0GB] [13:07:17] Topology snapshot [ver=16, servers=10, clients=0, CPUs=240, heap=99.0GB] 2) Only ignite clients are started and stopped in different Iterations. As we could see the client count becomes 0 and 1 whereas the servers count remain the same as 10 3) /tmp is a HDFS path where we have configured for Ignite and provided in cluster.properties. We could change this to any path. It would be helpful if there is a way to enable persistence in YARN deployment. Thank you.
