Subject [jira] Commented: (SOLR-1282) Replication handler's fetchindex command randomly ignores masterUrl parameter
Date Thu, 16 Jul 2009 04:23:14 GMT


Noble Paul commented on SOLR-1282:

hi Brian. I made those changes to the code (copying the object before spawning a new threda)
. SO the last nightly should have the fix

>                 URL:
>             Project: Solr
>          Issue Type: Bug
>          Components: replication (java)
>    Affects Versions: 1.4

> The fetchindex command of the replication handler is randomly ignoring the value of a
specified masterUrl parameter, instead using the masterUrl configured in solrconfig.xml.
> Injecting some debugging code shows that the contents of solrParams disappear sometime
after the thread running doSnapPull() starts in ReplicationHandler's handleRequestBody() method.
> This behavior is observed in the most recent nightly build (2009-07-14).
> How to replicate:
>     Configure a core as a slave with a masterUrl:
>         <requestHandler name="/replication" class="solr.ReplicationHandler">
>             <lst name="slave">
>                 <str name="masterUrl">http://dummy1</str>
>             </lst>
>         </requestHandler>
>     Run the core's fetchindex replication command several times, passing a different
>         /replication?command=fetchindex&masterUrl=http://dummy2
>     Logs show that the configured masterUrl (dummy1) is being used for at least half
the requests.
