Andrew Purtell resolved HBASE-3289.
-----------------------------------
Resolution: Incomplete
> EvictOnClose should be disabled when closing parent of split
> ------------------------------------------------------------
>
> Key: HBASE-3289
> URL: https://issues.apache.org/jira/browse/HBASE-3289
> Project: HBase
> Issue Type: Improvement
> Components: io, regionserver
> Reporter: Jonathan Gray
>
> EvictOnClose is now on by default. It doesn't make sense to evictOnClose
> when we close the parent files during a split. In that case, we will always
> open the files back up with Half readers on the same server immediately after
> closing them.
> Since we will do full reads of these files when we compact on the other side
> of the split, we should not evict the blocks when we close the initial parent.
> When both daughters of the original parent files have closed those files,
> then they should be evicted. This part is a bit tricky.
