Date Mon, 13 Jan 2014 10:28:57 GMT

    [ https://issues.apache.org/jira/browse/HBASE-10326?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13869408#comment-13869408

Anoop Sam John commented on HBASE-10326:

Patch looks good Ram.
Pls correct the white spaces introduced after checkIfScanOrGetFromSuperUser private method.
+    HTable acl = new HTable(conf, AccessControlLists.ACL_TABLE_NAME);
+    try {
+      BlockingRpcChannel service = acl.coprocessorService(tableName.getName());
+      AccessControlService.BlockingInterface protocol = AccessControlService
+          .newBlockingStub(service);
+      ProtobufUtil.grant(protocol, NORMAL_USER2.getShortName(), tableName, null, null,
+          Permission.Action.READ);
+    } finally {
+      acl.close();
+    }
Instead can use AccessControlClient#grant ?   This code is repeated in tests..

Thanks for the patch.

> This issue is in lieu with HBASE-10322.  In case of export tool, when the cells with
visibility labels are exported using a super user we should be able to export the data.  But
with the current implementation, the super user would also be able to view cells that has
visibility labels associated with the superuser.  The idea of HBASE-10322 is to strip out
tags based on user and if so this change is necessary for export tool to work with Visibility.
 ACL already has a concept of global admins.
