Prasanth Jayachandran commented on HIVE-16318:
----------------------------------------------
90-10 split for data-metadata is probably small. This may lead to some more
regression as queries will start reading file footers now. May be make the
split configurable and deprecate it so that it can be removed in 3.0 when
metadata moves offheap?

> We've run into HIVE-16233 and HIVE-15665 and given that 2.2 and 2.3 releases
> are approaching we are going to add workarounds for them, and then commit the
> above patches and revert the workarounds as soon as we can.
> Unfortunately this will result in cache wasting some memory on some datasets,
> but the alternatives, when they are encountered (usually only on large
> datasets), are worse.
