For RIT Duration, do better than print ms/seconds. Remove redundant UI
column dedicated to duration when we log it in the status field too.
Make bypass log at INFO level.
Make it so on complete of subprocedure, we note count of outstanding
siblings so we have a clue how much further the parent has to go before
it is done (Helpful when hundreds of servers doing SCP).
Have the SCP run the AP preflight check before creating an AP; saves
creation of thousands of APs during fixup.
Don't log tablename three times when reporting remote call failed.
If lock is held already, note who has it. Also log after we get lock
or if we have to wait rather than log on entrance though we may
later have to wait (or we may have just picked up the lock).

Adds override to assigns and unassigns. Changes bypass 'force'
to align calling the param 'override' instead.
Adds recursive to 'bypass', a means of calling bypass on
parent and its subprocedures (usually bypass works on
leaf nodes rippling the bypass up to parent -- recursive
has us work in the opposite direction): EXPERIMENTAL.
bypass on an assign/unassign leaves region in RIT and the
RegionStateNode loaded with the bypassed procedure. First
implementation had assign/unassign cleanup leftover state.
Second implementation, on feedback, keeps the state in place
as a fence against other Procedures assuming the region entity,
and instead adds an 'override' function that hbck2 can set on
assigns/unassigns to override the fencing.
Note that the below also converts ProcedureExceptions that
come out of the Pv2 system into DoNotRetryIOEs. It is a
little awkward because DNRIOE is in client-module, not
in procedure module. Previous, we'd just keep retrying
the bypass, etc.
M hbase-procedure/src/main/java/org/apache/hadoop/hbase/procedure2/Procedure.java
Have bypass take an environment like all other methods so subclasses.
Fix javadoc issues.
M hbase-procedure/src/main/java/org/apache/hadoop/hbase/procedure2/ProcedureExecutor.java
Javadoc issues. Pass environment when we invoke bypass.
M hbase-server/src/main/java/org/apache/hadoop/hbase/master/HMaster.java
Rename waitUntilNamespace... etc. to align with how these method types
are named elsehwere .. i.e. waitFor rather than waitUntil..
M hbase-server/src/main/java/org/apache/hadoop/hbase/master/assignment/RegionTransitionProcedure.java
Cleanup message we emit when we find an exisitng procedure working
against this entity.
Add support for a force function which allows Assigns/Unassigns force
ownership of the Region entity.
A hbase-server/src/test/java/org/apache/hadoop/hbase/master/assignment/TestRegionBypass.java
Test bypass and force.
M hbase-shell/src/main/ruby/shell/commands/list_procedures.rb
Minor cleanup of the json output... do iso8601 timestamps.
This reverts commit b96905d1df93aea0bc5b0e1ab074954e57b0dcc4.
i.e. a revert of a revert so a reapplication!
Revert so I can add signed-off-by....

Remove unused methods from Sleeper (its ok, its @Private).
Remove notion of startTime from Sleeper handling (it is is unused).
Allow passing in how long to sleep so can maintain externally.
In HRS, use a RetryCounter to calculate backoff sleep time for when
reportForDuty is failing against a struggling Master.
Recent versions of ZooKeeper whitelist the so-called 4-letter word admin
commands, and 'stat' is not in the default whitelist. Set system property
zookeeper.4lw.commands.whitelist=* in MiniZooKeeperCluster#setupTestEnv
as we do not need to whitelist 4-letter commands for unit tests.
Add a check for hbase:meta being online before we go to read it.
If not online, move into a holding-pattern until rectified, probably
by external operator.
Incorporates bulk of patch made by Allan Yang over on HBASE-21035.
M hbase-common/src/main/java/org/apache/hadoop/hbase/util/RetryCounterFactory.java
Add a Constructor for case where retries are for ever.
M hbase-server/src/main/java/org/apache/hadoop/hbase/master/HMaster.java
Move stuff around so that the first hbase:meta read is the AM#loadMeta.
Previously, checking table state and/or favored nodes could end up
trying to read a meta that was not onlined holding up master startup.
Do similar for the namespace table. Adds new methods isMeta and
isNamespace which check that the regions/tables are online.. if not,
we wait logging with a back-off that assigns need to be run.
