Replication handler's fetchindex command randomly ignores masterUrl parameter
-----------------------------------------------------------------------------
Key: SOLR-1282
URL: https://issues.apache.org/jira/browse/SOLR-1282
Project: Solr
Issue Type: Bug
Components: replication (java)
Affects Versions: 1.4
Reporter: Brian Loudon
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 masterUrl:
/replication?command=fetchindex&masterUrl=http://dummy2
Logs show that the configured masterUrl (dummy1) is being used for at least
half the requests.
