Listing Tables with the MapR-DB JSON Java API Library

List the JSON tables that are in a folder by calling an Admin object's listTables() method, passing as an argument the path of the folder.

Use a conditional loop to iterate through the returned list and retrieve the names of the tables.

Example

  public void listTables(String parentFolder) throws DBException {
    try (Admin admin = MapRDB.newAdmin()) {
      for(Path tablePath : admin.listTables(parentFolder)) {
        System.out.println(tablePath);
      }
    }
  }
Note: The parameter parentFolder provides a path to a folder that is in the MapR file system. See Table Paths for examples.

Permission Required

The readAce permission on the volumes where the JSON tables are located. For information about how to set permissions on volumes, see Setting/Modifying Whole Volume ACEs.
