[JBoss JIRA] (ISPN-4484) Outbound transfers can be cancelled by old CANCEL_STATE_TRANSFER command

by RH Bugzilla Integration (JIRA)

[ https://issues.jboss.org/browse/ISPN-4484?page=com.atlassian.jira.plugin.... ] RH Bugzilla Integration commented on ISPN-4484: ----------------------------------------------- Alan Field <afield(a)redhat.com> changed the Status of [bug 1104045|https://bugzilla.redhat.com/show_bug.cgi?id=1104045] from ON_QA to VERIFIED > Outbound transfers can be cancelled by old CANCEL_STATE_TRANSFER command > ------------------------------------------------------------------------ > > Key: ISPN-4484 > URL: https://issues.jboss.org/browse/ISPN-4484 > Project: Infinispan > Issue Type: Bug > Security Level: Public(Everyone can see) > Components: Core, State Transfer > Affects Versions: 6.0.2.Final > Reporter: Dan Berindei > Assignee: Dan Berindei > Priority: Critical > Fix For: 7.0.0.Alpha5 > > > This appeared during the 32-nodes elasticity test in the Hyperion environment. > Just as apex947 left, it started a rebalance, which apex948 dutifully cancelled as it became the new coordinator. apex949 had already requested segments from apex959, so it sent a StateRequestCommand(CANCEL_STATE_TRANSFER) asynchronously to apex959. Then apex948 started a new rebalance, and apex949 asked apex959 for the same segments. When apex959 finally received the cancel request, it didn't check the topology id and it incorrectly cancelled the outbound transfer to apex949. > The solution would be to verify the topology id in the CANCEL_STATE_TRANSFER command before cancelling the transfer. I also think we can avoid sending the cancel command completely in this case, and only send it as we are about to stop. -- This message was sent by Atlassian JIRA (v6.2.6#6264)

[JBoss JIRA] (ISPN-4490) Members can miss the rebalance cancellation on coordinator change

by RH Bugzilla Integration (JIRA)

But the CH_UPDATE command is sent asynchronously, so it's possible for some members to receive it after the REBALANCE_START command. > If that happens, that node will assume that it will receive the segments it requested for the previous rebalance. But with the ISPN-4484 fix, the provider node cancels the outbound transfer tasks when receiving a CH_UPDATE without a pendingCH, so the state requestor will never receive its segments. > Even without the ISPN-4484 fix this is a problem, although less obvious. Between the provider node receiving the CH_UPDATE and the REBALANCE_START commands, it won't have the requestor in its write CH, so the requestor can miss transactions. -- This message was sent by Atlassian JIRA (v6.2.6#6264)

[JBoss JIRA] (ISPN-4154) Cancelled segment transfer causes future entry transfer to be ignored
