Subject [jira] [Updated] (SOLR-6145) Concurrent Schema API field additions can result in endless loop
Date Tue, 10 Jun 2014 19:39:03 GMT

     [ https://issues.apache.org/jira/browse/SOLR-6145?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Steve Rowe updated SOLR-6145:
-----------------------------

    Attachment: SOLR-6145.patch

Patch, removes the useless optimistic concurrency loops from ManagedIndexSchema.add(Copy)Fields(),
and also modifies the consumers of those methods to handle failures that won't benefit from
retrying.

Committing shortly.
