Description

ClientScanner will create HConnection in its construction:

    public ClientScanner(final Configuration conf, final Scan scan,
        final byte[] tableName) throws IOException {
      this(conf, scan, tableName, HConnectionManager.getConnection(conf));
    }

However, this connection won't be closed in ClientScanner.close(). Is it better to deprecate this construction?
