+Set the visibility expression on one or more existing cells.
+
+Pass table name, visibility expression, and a dictionary containing
+scanner specifications.  Scanner specifications may include one or more
+of: TIMERANGE, FILTER, STARTROW, STOPROW, TIMESTAMP, or COLUMNS
+
+If no columns are specified, all columns will be included.
+To include all members of a column family, leave the qualifier empty as in
+'col_family:'.
+
+The filter can be specified in two ways:
+1. Using a filterString - more information on this is available in the
+Filter Language document attached to the HBASE-4176 JIRA
+2. Using the entire package name of the filter.
+
+Examples:
+
+    hbase> set_visibility 't1', 'A|B', {COLUMNS => ['c1', 'c2']}
+    hbase> set_visibility 't1', '(A&B)|C', {COLUMNS => 'c1',
+        TIMERANGE => [1303668804, 1303668904]}
+    hbase> set_visibility 't1', 'A&B&C', {FILTER => "(PrefixFilter ('row2') AND
+        (QualifierFilter (>=, 'binary:xyz'))) AND
+        (TimestampsFilter ( 123, 456))"}
+
+This command will only affect existing cells and is expected to be mainly
+useful for feature testing and functional verification.
