### v1.3+ versions

Version 1.3 introduces changes to help with [faster metadata reads and updates](https://blog.min.io/minio-versioning-metadata-deep-dive/)

/**
 * Example of using a hardware key to perform client auth.
 * Prefer recent JDK builds, and results are temperamental to slight environment changes.
 * Different instructions and configuration may be required for other hardware devices.
 *
 * Using a yubikey device as a SSL key store.

need to customize SSL, do so for your specific OkHttpClient instance only.

##### Synthetic headers have changed

Previously OkHttp added a synthetic response header, `OkHttp-Selected-Transport`. It
has been replaced with a new synthetic header, `OkHttp-Selected-Protocol`.

##### Changes

 * New: Support for `HTTP-draft-09/2.0`.
 * New: Support for `spdy/3.1`. Dropped support for `spdy/3`.

     * The entrySet() of ConcurrentHashMap, unlike that of other Map
     * implementations, supports add() under JDK8. This seems problematic, but I
     * didn't see that discussed in the review, which included many other
     * changes: https://mail.openjdk.org/pipermail/core-libs-dev/2013-May/thread.html#17367
     *
     * TODO(cpovirk): decide what the best long-term action here is: force users

      Map<K, Collection<V>> asMap(Multimap<K, V> multimap) {
    return multimap.asMap();
  }

  /**
   * Returns a multimap view of the specified map. The multimap is backed by the map, so changes to
   * the map are reflected in the multimap, and vice versa. If the map is modified while an
   * iteration over one of the multimap's collection views is in progress (except through the

    List<List<Integer>> partitions = partition(list, 3);

    // Changes before the partition is retrieved are reflected
    list.set(0, 3);

    Iterator<List<Integer>> iterator = partitions.iterator();

    // Changes before the partition is retrieved are reflected
    list.set(1, 4);

    List<Integer> first = iterator.next();

    // Changes after are too (unlike Iterables.partition)
    list.set(2, 5);

 *
 * The configuration of each spec changes with each OkHttp release. This is annoying: upgrading
 * your OkHttp library can break connectivity to certain web servers! But it’s a necessary annoyance
 * because the TLS ecosystem is dynamic and staying up to date is necessary to stay secure. See
 * [OkHttp's TLS Configuration History][tls_history] to track these changes.

Once the config changes are applied, proceed to restart **Hadoop** services.
