Pavel Voronkin updated IGNITE-10511:
------------------------------------
Description:
See attached thread dump:
disco-event-worker hangs on removeExplicitNodeLocks() on GridCacheMapEntry
which is held by GridDistributedTxRemoteAdapter acquired in
GridCacheMapEntry.innerSet().
CacheObjectBinaryProcessorImpl is waiting on metadata message on discovery,
which can be processed due to disco-event-worker is stuck.
Possible fix:
public void onNodeLeft(final ClusterNode node) {
if (isDone() || !enterBusy())
return;
cctx.mvcc().removeExplicitNodeLocks(node.id(), initialVersion());
try {
onDiscoveryEvent(new IgniteRunnable() {
@Override public void run() {
if (isDone() || !enterBusy())
return;
As we can see most of the processing is done async in IgniteRunnable() in
exchange-worker.
We can move
{quote}cctx.mvcc().removeExplicitNodeLocks(node.id(), initialVersion());
{quote}
inside this Runnable's body.
