    Description

      Before bumping to ORC-1.6, LLAP_ALLOCATOR_MAX_ALLOC value was also used as the ORC CacheWriter buffer size.

      As per ORC-238, the max bufferSize argument can be up to 2^(3*8 - 1) – i.e., less than 8Mb.

      In HIVE-23553 we decouple the two configuration (LLAP max alloc and CacheWriter buffer size) – this ticket is to investigate if there is a need for these two conf to converge.
