[jira] [Created] (IGNITE-8372) Cluster metrics are reported
incorrectly on joining node with ZK-based discovery
Sergey Chugunov created IGNITE-8372:
---------------------------------------
Summary: Cluster metrics are reported incorrectly on joining node with ZK-based discovery
Key: IGNITE-8372
URL: https://issues.apache.org/jira/browse/IGNITE-8372
Project: Ignite
Issue Type: Bug
Components: zookeeper
Reporter: Sergey Chugunov
Assignee: Sergey Chugunov
Fix For: 2.5
When new node joins with ZK discovery it sometimes reports negative number of CPUs and incorrect heap size.
Message in log looks like this:
{noformat}
[myid:] - INFO [disco-event-worker-#61:Log4JLogger@495] - Topology snapshot [ver=100, servers=100, clients=0, CPUs=-6, heap=0.5GB]
{noformat}
There is a race though between this report and ClusterMetricsUpdateMessage: if the node receives and process this message first which happens in a separate thread correct values are printed to log.
