[jira] [Created] (HBASE-14549) Simplify scanner stack reset logic

Lars Hofhansl created HBASE-14549:
-------------------------------------

             Summary: Simplify scanner stack reset logic
                 Key: HBASE-14549
                 URL: https://issues.apache.org/jira/browse/HBASE-14549
             Project: HBase
          Issue Type: Bug
            Reporter: Lars Hofhansl
            Assignee: Lars Hofhansl


Looking at the code, I find that the logic is unnecessarily complex.
We indicate in updateReaders that the scanner stack needs to be reset. Than almost all store scanner (and derived classes) methods need to check and actually reset the scanner stack.
Compaction are rare, we should reset the scanner stack in update readers, and hence avoid needing to check in all methods.

Patch forthcoming.
