> {noformat}
> HBASE-8300 tried to fix this issue by adding 'StoreFile#closeReader()' call. However, after the open reader calls, there are 4 'return null' calls before the close call. When I run TestSplitTransaction#testWholesomeSplit(), 2 of the 'return null' calls were hit multiple times (which means the opened file is not closed).
> The fix needs to make sure that StoreFile#closeReader() is called in all situation.
