------------------------------------------
Summary: NPE on a try to get a RAFT node's striped executor pool
Key: IGNITE-20032
URL: https://issues.apache.org/jira/browse/IGNITE-20032
Project: Ignite
Issue Type: Bug
Reporter: Vladislav Pyatkov
Stopping the striped pool can happen earlier than the last RPC messafe is
processed.
Just after the pool is stopped, its reference is reset to {{null}}:
{code:java|title=org.apache.ignite.raft.jraft.core.NodeImpl#join|borderStyle=solid}
if (opts.getStripedExecutor() != null && !opts.isSharedPools()) {
opts.getStripedExecutor().shutdownGracefully();
opts.setStripedExecutor(null);
}
{code}
