Andrew Mashenkov commented on IGNITE-4142: ------------------------------------------ TC tests look good. > Assertion in ClientImpl.updateMetrics() > --------------------------------------- > > Key: IGNITE-4142 > URL: https://issues.apache.org/jira/browse/IGNITE-4142 > Project: Ignite > Issue Type: Bug > Components: general > Affects Versions: 1.7 > Reporter: Valentin Kulichenko > Assignee: Andrew Mashenkov > Priority: Critical > Fix For: 2.0 > > > The problem was reported here: > http://apache-ignite-users.70518.x6.nabble.com/AssertionError-td8321.html > It looks like the reason is that > {{TcpDiscoveryHeartbeatMessage.setCacheMetrics()}} method does not put empty > map in the {{cacheMetrics}} collection. As a result, it's possible that there > are cluster metrics for a node, but no cache metrics for this node - this > leads to the assertion in {{ClientImpl.updateMetrics}} (see below). We should > remove the {{if}} in {{TcpDiscoveryHeartbeatMessage.setCacheMetrics()}} or > change {{ClientImpl.updateMetrics}} logic so that it does not fail in this > case. > We should also try to reproduce in a unit test to make sure this the only > problematic code here. > {noformat} > 10:39:38,355 SEVERE [TcpDiscoverySpi] Runtime error caught during grid > runnable execution: IgniteSpiThread > [name=tcp-client-disco-msg-worker-#4%FooGrid%]: java.lang.AssertionError > at > org.apache.ignite.spi.discovery.tcp.ClientImpl$MessageWorker.updateMetrics(ClientImpl.java:2046) > > at > org.apache.ignite.spi.discovery.tcp.ClientImpl$MessageWorker.processHeartbeatMessage(ClientImpl.java:1926) > > at > org.apache.ignite.spi.discovery.tcp.ClientImpl$MessageWorker.processDiscoveryMessage(ClientImpl.java:1580) > > at > org.apache.ignite.spi.discovery.tcp.ClientImpl$MessageWorker.body(ClientImpl.java:1499) > > at org.apache.ignite.spi.IgniteSpiThread.run(IgniteSpiThread.java:62) > {noformat} -- This message was sent by Atlassian JIRA (v6.3.4#6332)
