Methods in org.apache.hadoop.hbase.io that return ByteBuffAllocator

Modifier and Type	Method and Description
static ByteBuffAllocator	ByteBuffAllocator.create(org.apache.hadoop.conf.Configuration conf, boolean reservoirEnabled) Initialize an ByteBuffAllocator which will try to allocate ByteBuffers from off-heap if reservoir is enabled and the reservoir has enough buffers, otherwise the allocator will just allocate the insufficient buffers from on-heap to meet the requirement.
