----------------------------------------
Summary: Block cache reserves section for in-memory blocks
Key: ACCUMULO-2008
URL: https://issues.apache.org/jira/browse/ACCUMULO-2008
Project: Accumulo
Issue Type: Bug
Components: tserver
Affects Versions: 1.5.0, 1.4.4, 1.6.0
Reporter: Billie Rinaldi
Fix For: 1.7.0
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.
