---------------------------------
Summary: You should be able to use one pool of memory for multiple collection's HDFS block caches.
Key: SOLR-5714
URL: https://issues.apache.org/jira/browse/SOLR-5714
Project: Solr
Issue Type: Improvement
Reporter: Mark Miller
Assignee: Mark Miller
Fix For: 5.0, 4.7
Currently, you have to specify how much direct memory to allocate per collection. This can be inefficient, and has some negative consequences - for instance, when replicating, many times two HDFS directories will exist for the same index briefly, which will double the RAM used for that SolrCore.
