Anoop Sam John commented on HBASE-10451:
----------------------------------------
Yes Ted. It is intended. 0.98 went with size as Short.Max for the LRUDict for
tags in case of WAL.. For HFiles any way he had disabled that due to a defect.
(Which we are solving here)
But having this much size for tags will be too much we feel. Also in case of
HFiles there can be many parallel files read/write and each creating this much
big LRUDict will be overkill. So it will be better to use Byte.Max (as we do
with Qualifier Dict for WAL)
Because of BC for 0.98 written WAL we continue to use Short.Max in case of WAL .
