Subject [jira] [Commented] (HBASE-13370) PE tool could give option for using Explicit Column Tracker which leads to seeks
Date Thu, 02 Apr 2015 05:03:52 GMT

    [ https://issues.apache.org/jira/browse/HBASE-13370?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14392156#comment-14392156

Srikanth Srungarapu commented on HBASE-13370:
---------------------------------------------

Looks like this block is missing in latest patch.
{code}
+      final String addColumns = "--addColumns=";
+      if (cmd.startsWith(addColumns)) {
+        opts.addColumns = Boolean.parseBoolean(cmd.substring(addColumns.length()));
+        continue;
+      }
{code}
And also, this should {{Default : true}} -> {{Default: true}} as per conventions being
followed in PE.

> Currently in PE tool all the scans and gets adds explicitly the columns to be scanned.
 The tool by default adds only one Qualifier.  Doing this addColumns leads to Explicit Column
Tracker which does seeks frequently. If we want to know a simple scan performance as a basic
scenario then we should have the option to add this columns explicitly.
