Subject [jira] [Commented] (HBASE-17917) Use pread by default for all user scan
Date Wed, 26 Apr 2017 02:46:04 GMT

    [ https://issues.apache.org/jira/browse/HBASE-17917?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15984083#comment-15984083

Duo Zhang commented on HBASE-17917:
-----------------------------------

I misunderstood the meaning of checkReseek method, it will not reopen the old StoreFileScanners...
So I need to implement my own method.

And I did find some problems for the implementation of checkReseek. Let me open new issues
to track them.

Thanks.
