Subject [jira] [Updated] (SOLR-5656) Add autoAddReplicas feature for shared file systems.
Date Mon, 11 Aug 2014 20:34:13 GMT

     [ https://issues.apache.org/jira/browse/SOLR-5656?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Mark Miller updated SOLR-5656:
------------------------------

    Description: 
When using HDFS, the Overseer should have the ability to reassign the cores from failed nodes
to running nodes.

Given that the index and transaction logs are in hdfs, it's simple for surviving hardware
to take over serving cores for failed hardware.

There are some tricky issues around having the Overseer handle this for you, but seems a simple
first pass is not too difficult.

This will add another alternative to replicating both with hdfs and solr.

It shouldn't be specific to hdfs, and would be an option for any shared file system Solr supports.
