--------------------------------------------
Summary: [LLAP] Preallocate arenas for mmap case as well
Key: HIVE-23476
URL: https://issues.apache.org/jira/browse/HIVE-23476
Project: Hive
Issue Type: Bug
Reporter: Prasanth Jayachandran
Assignee: Prasanth Jayachandran
BuddyAllocator pre-allocation of arenas does not happen for mmap cache case.
Since we are not filling up the mmap'ed buffers the upfront allocations in
constructor is cheap. This can avoid lock free allocation of arenas later in
the code.
