      Description

      The block cache reserves a quarter of its size for in-memory blocks, but Accumulo doesn't have any in-memory blocks. This makes the cache size parameters misleading, because the cache will effectively end up using 75% of its specified size. This could be fixed by changing the default percentages in LruBlockCache, or by using the constructor takes the percentages as parameters.
