light queue is actually buggy, so re-enabling the config. however, if anyone is ok with the buggy behavior, made the max time lost due to light queue configurable. We want to get to making the ligth queue default if we can make it work perfectly. also applying neighbor optimizations to use the faster method for light checks.

Subject: [PATCH] Sanitise RegionFileCache and make configurable.
|
|
|
|
RegionFileCache prior to this patch would close every single open region
|
|
file upon reaching a size of 256.
|
|
This patch modifies that behaviour so it closes the the least recently
|
|
used RegionFile.
|
|
The implementation uses a LinkedHashMap as an LRU cache (modified from HashMap).
|
|
The maximum size of the RegionFileCache is also made configurable.
