[infinispan-issues] [JBoss JIRA] (ISPN-1942) State transfer timeout confusion

[Dan Berindei (JIRA)]

    [ https://issues.jboss.org/browse/ISPN-1942?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12679479#comment-12679479 ] 

Dan Berindei commented on ISPN-1942:
------------------------------------

1. Agree, we should make the user remove the deprecated stuff when moving to the `stateTransfer` configuration.

2. `hash.rehashRpcTimeout` should have been equivalent to `stateTransfer.timeout` and `stateRetrieval.timeout`. However, I missed something in the LegacyConfigurationAdapter (namely the use of the `activated` flag) and this meant the `stateTransfer` settings are ignored when the configuration is adapted to the old style.

Ideally you should only need to use `stateTransfer` and `global.transport.distributedSyncTimeout` (which I forgot to give a more relevant name in 5.1). The old settings are only needed now because of the configuration translation bug.

> 1. The XML file should not allow both stateRetrieval (deprecated) and stateTransfer to be defined:

> 2. In spite of setting the stateTransfer timeout, state transfer is looking for hash.rehashRpcTimeout which by default is 10 minutes? @Dan, shouldn't the state transfer timeout be passed onto the hash.rehashTimeout? 
> Also @Dan, do we have any docu on how this really should be configured in 5.1?
