[jira] [Commented] (KNOX-1237) Knox DSL should support HBase Stateless Scanner
[ https://issues.apache.org/jira/browse/KNOX-1237?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel=16746435#comment-16746435 ] Dequan Chen commented on KNOX-1237: --- [~risdenk]: The implementation of the Knox Shell HBase stateless scanner is to use a temporary stateful scanner ID to get all the data of a user's request by >=1 step(s) and return the complete data to the user depending on the request (version #, columns, rows etc). So the user does not need to create any stateful scanner(s) to loop through all possible steps for each step's data + combining the data as a whole Therefore, the user does not see any stateful scanner action because of the encapsulation adopted in the object-oriented implementation. Hope that the explanation helps you understand that.

Kevin Risden commented on KNOX-1237:
[~dequanchen] while looking through the patch I see the following line
while (!(tempValue =
HBase.session(session).table(tableName).scanner(scannerId).getNext().now().getString()).isEmpty())
{ +
This looks like it creates a stateful scanner from within the stateless
scanner? That doesn't seem correct to me. There should be no reason to have any
Scanner ID from within the stateless scanner.
