Mark Miller updated SOLR-5714:
------------------------------
Description: Currently, you have to specify how much direct memory to
allocate per SolrCore. 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. (was: Currently, you have to specify how much direct memory to

. 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.)
> You should be able to use one pool of memory for multiple collection's HDFS
> block caches.
