Error while connecting 2 nodes in grid in Apache Ignite

I am getting following error while connecting 2 nodes in grid in Apache Ignite. These 2 nodes detect themselves when I run script ignite.sh on both nodes. But when I try to start ignite on one node using ignite.sh and on another node using java code, I am getting following error.

Solution

  • See the root cause:

    Remote node has peer class loading enabled flag different from local [locId8=d9ec5b41, locPeerClassLoading=true, rmtId8=3d11ed2e, rmtPeerClassLoading=false
    • ignite.sh starts a node with peerClassLoading disabled
    • your Java code starts a node with peerClassLoading enabled

    Make sure that IgniteConfiguration.peerClassLoading properties match.
