MapReduce Indexer can error when using secure collection



    • Type: Bug
    • Status: Closed
    • Priority: Major
    • Resolution: Won't Fix

    • Fix Version/s: None
    • Component/s: contrib - MapReduce
    • Labels:


      When running the MapReduceIndexerTool, it will usually pull a solrconfig.xml from ZK for the collection that it is running against. This can be problematic for several reasons:

      • Performance: The configuration in ZK will likely have several query handlers, and lots of other components that don't make sense in an indexing-only use of EmbeddedSolrServer (ESS).
      • Classpath Resources: If the Solr services are using some kind of additional service (such as Sentry for auth) then the indexer will not have access to the necessary configurations without the user jumping through several hoops.
      • Distinct Configuration Needs: Enabling Soft Commits on the ESS doesn't make sense. There's other configurations that
      • Update Chain Behaviours: I'm under the impression that UpdateChains may behave differently in ESS than a SolrCloud cluster. Is it safe to depend on consistent behaviour here?
