[jira] [Updated] (KNOX-1237) Knox DSL should support HBase Stateless Scanner

     [ https://issues.apache.org/jira/browse/KNOX-1237?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Kevin Risden updated KNOX-1237:
-------------------------------
    Description: 
KNOX-8 added support for HBase REST apis via Knox. The Knox DSL supports stateful scanners as shown in the documentation (https://knox.apache.org/books/knox-1-0-0/user-guide.html#table(String+tableName).scanner().create()+-+Scanner+Creation).

HBase REST supports stateless scanners ([https://hbase.apache.org/1.2/apidocs/org/apache/hadoop/hbase/rest/package-summary.html#operation_stateless_scanner]) which can be easily load balanced. The feature is not well documented in HBase REST.

Currently if using stateful scanners and Knox or HBase REST is being load balanced, there will be an issue using that scanner. The stateless scanners avoid this since they have all the information necessary.
