Subject [jira] [Created] (HBASE-18122) Scanner id should include more information
Date Fri, 26 May 2017 07:23:05 GMT
Phil Yang created HBASE-18122:

             Summary: Scanner id should include more information
                 Key: HBASE-18122
                 URL: https://issues.apache.org/jira/browse/HBASE-18122
             Project: HBase
          Issue Type: Bug
            Reporter: Phil Yang
            Assignee: Phil Yang

Now the scanner id is a long number from 1 to max in a region server. Each new scanner will
have a scanner id.
If a client has a scanner whose id is x, when the RS restart and the scanner id is also incremented
to x or a little larger, there will be a scanner id collision.
So the scanner id should now be same during each time the RS restart. We can add the start
timestamp as the highest several bits in scanner id uint64.
