unreachable to each other
ventsislav created CASSANDRA-14924:
--------------------------------------
Summary: Cassandra nodes becomes unreachable to each other
Key: CASSANDRA-14924
URL: https://issues.apache.org/jira/browse/CASSANDRA-14924
Project: Cassandra
Issue Type: Bug
Reporter: ventsislav
I have 3 nodes of elassandra running in docker containers.
Containers created like:
> Host 10.0.0.1 : docker run --name elassandra-node-1 --net=host -e CASSANDRA_SEEDS="10.0.0.1" -e CASSANDRA_CLUSTER_NAME="BD Storage" -e CASSANDRA_DC="DC1" -e CASSANDRA_RACK="r1" -d strapdata/elassandra:latest
> Host 10.0.0.2 : docker run --name elassandra-node-2 --net=host -e CASSANDRA_SEEDS="10.0.0.1,10.0.0.2" -e CASSANDRA_CLUSTER_NAME="BD Storage" -e CASSANDRA_DC="DC1" -e CASSANDRA_RACK="r1" -d strapdata/elassandra:latest
> Host 10.0.0.3 : docker run --name elassandra-node-3 --net=host -e CASSANDRA_SEEDS="10.0.0.1,10.0.0.2,10.0.0.3" -e CASSANDRA_CLUSTER_NAME="BD Storage" -e CASSANDRA_DC="DC1" -e CASSANDRA_RACK="r1" -d strapdata/elassandra:latest
Cluster was working fine for a couple of days since created, elastic, cassandra all was perfect.
Currently however all cassandra nodes became unreachable to each other:
Nodetool status on all nodes is like
> Datacenter: DC1
> ===============
> Status=Up/Down
> |/ State=Normal/Leaving/Joining/Moving
> -- Address Load Tokens Owns (effective) Host ID Rack
> DN 10.0.0.3 11.95 GiB 8 100.0% 7652f66e-194e-4886-ac10-0fc21ac8afeb r1
> DN 10.0.0.2 11.92 GiB 8 100.0% b91fa129-1dd0-4cf8-be96-9c06b23daac6 r1
> UN 10.0.0.1 11.9 GiB 8 100.0% 5c1afcff-b0aa-4985-a3cc-7f932056c08f r1
Where the UN is the current host 10.0.0.1
Same on all other nodes.
Nodetool describecluster on 10.0.0.1 is like
> Cluster Information:
> Name: BD Storage
> Snitch: org.apache.cassandra.locator.GossipingPropertyFileSnitch
> DynamicEndPointSnitch: enabled
> Partitioner: org.apache.cassandra.dht.Murmur3Partitioner
> Schema versions:
> 24fa5e55-3935-3c0e-9808-99ce502fe98d: [10.0.0.1]
>
> UNREACHABLE: [10.0.0.2,10.0.0.3]
When attached to the first node its only repeating these infos:
> 2018-12-09 07:47:32,927 WARN [OptionalTasks:1] org.apache.cassandra.auth.CassandraRoleManager.setupDefaultRole(CassandraRoleManager.java:361) CassandraRoleManager skipped default role setup: some nodes were not ready
> 2018-12-09 07:47:32,927 INFO [OptionalTasks:1] org.apache.cassandra.auth.CassandraRoleManager$4.run(CassandraRoleManager.java:400) Setup task failed with error, rescheduling
> 2018-12-09 07:47:32,980 INFO [HANDSHAKE-/10.0.0.2] org.apache.cassandra.net.OutboundTcpConnection.lambda$handshakeVersion$1(OutboundTcpConnection.java:561) Handshaking version with /10.0.0.2
> 2018-12-09 07:47:32,980 INFO [HANDSHAKE-/10.0.0.3] org.apache.cassandra.net.OutboundTcpConnection.lambda$handshakeVersion$1(OutboundTcpConnection.java:561) Handshaking version with /10.0.0.3
After a while when some node is restarted:
> 2018-12-09 07:52:21,972 WARN [MigrationStage:1] org.apache.cassandra.service.MigrationTask.runMayThrow(MigrationTask.java:67) Can't send schema pull request: node /10.0.0.2 is down.
Tried so far:
Restarting all containers at the same time
Restarting all containers one after another
Restarting cassandra in all containers like : service cassandra restart
Nodetool disablegossip then enable it
Nodetool repair : Repair command #1 failed with error Endpoint not alive: /10.0.0.2
Seems that all node schemas are different, but I still dont understand why they are marked as down to each other.
