Network identities should be bound late. Remote addresses should be
resolved at the last possible moment, just before connect(). Network
identity mappings can change, so our code should not inappropriately
cache them. Otherwise we might miss a change and fail to operate normally.
Revert "HBASE-14544 Allow HConnectionImpl to not refresh the dns on errors"
Removes hbase.resolve.hostnames.on.failure and related code. We always
resolve hostnames, as late as possible.
Preserve InetSocketAddress caching per RPC connection. Avoids potential
lookups per Call.
Replace InetSocketAddress with Address where used as a map key. If we want
to key by hostname and/or resolved address we should be explicit about it.
Using Address chooses mapping by hostname and port only.
Add metrics for potential nameservice resolution attempts, whenever an
InetSocketAddress is instantiated for connect; and metrics for failed
resolution, whenever InetSocketAddress#isUnresolved on the new instance
is true.
* Use ServerName directly to build a stub key
* Resolve and cache ISA on a RpcChannel as late as possible, at first call
* Remove now invalid unit test TestCIBadHostname
We resolve DNS at the latest possible time, at first call, and do not
resolve hostnames for creating stubs at all, so this unit test cannot
work now.

This PR is a follow-up of HBASE-25181 (#2539), where several issues were
discussed on the PR:
1. Currently we use PBKDF2WithHmacSHA1 key generation algorithm to generate a
secret key for HFile / WalFile encryption, when the user is defining a string
encryption key in the hbase shell. This algorithm is not secure enough and
not allowed in certain environments (e.g. on FIPS compliant clusters). We are
changing it to PBKDF2WithHmacSHA384. It will not break backward-compatibility,
as even the tables created by the shell using the new algorithm will be able
to load (e.g. during bulkload / replication) the HFiles serialized with the
key generated by an old algorithm, as the HFiles themselves already contain
the key necessary for their decryption.
Smaller issues fixed by this commit:
2. Improve the documentation e.g. with the changes introduced by HBASE-25181
and also by some points discussed on the Jira ticket of HBASE-25263.
3. In EncryptionUtil.createEncryptionContext the various encryption config
checks should throw IllegalStateExceptions instead of RuntimeExceptions.
4. Test cases in TestEncryptionTest.java should be broken down into smaller
tests.
5. TestEncryptionDisabled.java should use ExpectedException JUnit rule to
validate exceptions.

* PoolMap does not discard any elements anymore. If an element is put,
it always stores it. The reason: it stores expensive resources (rpc
connections) which would lead to resource leak if we simple discard it.
RpcClients can reference netty ByteBufs which are reference counted.
Resource cleanup is done by AbstractRpcClient.cleanupIdleConnections().
* PoolMap does not implement Map interface anymore, so ensuring
thread-safety has become easier. Put method is replaced with getOrCreate().
* ThreadLocalPool doesn't use ThreadLocal class anymore. It stores
resources on thread basis, but it doesn't remove values when a thread
exits. Again, proper cleanup is done by cleanupIdleConnections().

Clean up the read replica of META doc. Introduce the new read replica
liveness on META and the new 'LoadBalance' feature (with warnings).
General edit.
It adds load balance support for meta lookup in AsyncTableRegionLocator.
The existing meta replica mode is renamed as "HedgedRead", client sends scan request to the primary meta replica region first,
if response is not back within a configured amount of time, it will send scan requests to all meta replica regions and
take the first response. On top of the existing mode, a new mode "LoadBalance" is introduced. In this mode, client first
choose a meta replica region to send scan request. If the response is stale, it may send the request to another meta replica region or
the primary region. In this mode, meta scan requests are load balanced across all replica regions with the primary mode as
the ultimate source of truth.
Two new config knobs are added:
1. hbase.locator.meta.replicas.mode
Valid options are "None", "HedgedRead" and "LoadBalance", they are case insensitive. The default mode is "None".
2. hbase.locator.meta.replicas.mode.loadbalance.selector
The load balance alogrithm to select a meta replica to send the requests.
Only org.apache.hadoop.hbase.client.CatalogReplicaLoadBalanceReplicaSimpleSelector.class
is supported for now, which is the default as well. The algorithm works as follows:
a. Clients select a randome meta replica region to send the requests if there is no entry for the location in the stale
location cache.
b. If the location from one meta replica region is stale, a stale entry will be created in the statle location cache
for the region.
c. Clients select the primary meta region if the location is in the stale location cache.
d. The stale location cache entries time out in 3 seconds.
If there is no "hbase.locator.meta.replicas.mode" configured, it will check the config knob "hbase.meta.replicas.use".
If "hbase.meta.replicas.use" is configured, the mode will be set to "HedgedRead".
Prior to this patch hbase always used the MD5 hash algorithm to store a hash for encryption keys.
This hash is needed to verify the secret key of the subject. (e.g. making
sure that the same secrey key is used during encrypted HFile read and write).
The MD5 algorithm is considered weak, and can not be used in some
(e.g. FIPS compliant) clusters.
In this patch we:
- add a config parameter to globally enable/disable column family encryption (def enabled)
- introduce a backward compatible way of specifying the hash algorithm.
This enable us to use newer and more secure hash algorithms like SHA-384
or SHA-512 (which are FIPS compliant).
- add a config parameter to fail if an hfile is encountered that uses a
different hash algorithm than the one currently configured to ease validation after
migrating key hash algorithms (def disabled)

This patch adds the ability to discover newly added masters
dynamically on the master registry side. The trigger for the
re-fetch is either periodic (5 mins) or any registry RPC failure.
Master server information is cached in masters to avoid repeated
ZK lookups.
Updates the client side connection metrics to maintain a counter
per RPC type so that clients have visibility into counts grouped
by RPC method name.
I didn't add the method to ZK registry interface since there
is a design discussion going on in splittable meta doc. We can
add it later if needed.

The PLAIN mechanism test added in the Shade authentication example has
different semantics than GSSAPI mechanism -- the client reports that the
handshake is done after the original challenge is computed. The javadoc
on SaslClient, however, tells us that we need to wait for a response
from the server before proceeding.
The client, best as I can see, does not receive any data from HBase;
however the application semantics (e.g. throw an exception on auth'n
error) do not work as we intend as a result of this bug.
Extra trace logging was also added to debug this, should a similar error
ever happen again with some other mechanism.
