Elliott Clark updated HBASE-14793:
----------------------------------
Release Note: Very large blocks can fragment the heap and cause bad issues
for the garbage collector, especially the G1GC. Now there is a maximum size
that a block can be and still stick in the LruBlockCache. That size defaults to
16mb but can be controlled by changing "hbase.lru.max.block.size"
> Allow limiting size of block into L1 block cache.
