Jonathan Gray updated HBASE-1192:
---------------------------------
Attachment: hbase-1192-v2.patch
Built from latest LruHashMap, this is a specialized version that only works for
<String,ByteBuffer>
This is so we don't have to have wrapping classes that implement HeapSize for
the key and val (req for LruHashMap).
Needs testing but is expected to work, very few changes.
This patch has a dependency of latest HeapSize as posted in most recent
HBASE-1186 v4 patch.
