A miscellaney. Add extra logging to help w/ debug to a bunch of tests.
Fix some issues particular where we ran into mismatched filesystem
complaint. Some modernizations, removal of unnecessary deletes
(especially after seeing tests fail in table delete), and cleanup.
Recategorized one tests because it starts four clusters in the one
JVM from medium to large. Finally, zk standalone server won't come
on occasion; added debug and thread dumping to help figure why (
manifests as test failing in startup saying master didn't launch).
hbase-mapreduce/src/test/java/org/apache/hadoop/hbase/snapshot/TestExportSnapshot.java
Fixes occasional mismatched filesystems where the difference is file:// vs file:///
or we pick up hdfs schema when it a local fs test. Had to do this
vetting of how we do make qualified on a Path in a few places, not
just here as a few tests failed with this same issue. Code in here is
used by a lot of tests that each in turn suffered this mismatch.
Refactor for clarity
hbase-mapreduce/src/test/java/org/apache/hadoop/hbase/snapshot/TestExportSnapshotV1NoCluster.java
Unused import.
hbase-procedure/src/test/java/org/apache/hadoop/hbase/procedure2/store/wal/TestWALProcedureStore.java
This test fails if tmp dir is not where it expects because tries to
make rootdir there. Give it a rootdir under test data dir.

This change is probably useless. I think the issue is actually
a problem addressed later where our test for zk server being
up gets stuck and never times out.

Don't bother removing stuff on teardown. All gets thrown away anyways.
Saw a few hangs in here in the teardown where hdfs was down before
expected messing up shutdown.

Add timeout on socket; was seeing check for zk server getting stuck
and never timing out (test time out in startup)

Write to test data dir instead.
Be careful about how we make qualified paths.

Remove snowflake configs.
hbase-server/src/test/java/org/apache/hadoop/hbase/replication/TestReplicationStatus.java
Add a hacky pause. Tried adding barriers but didn't work. Needs deep
dive.
hbase-zookeeper/src/main/java/org/apache/hadoop/hbase/zookeeper/MiniZooKeeperCluster.java
Remove code copied from zk and use zk methods directly instead.
A general problem is that zk cluster doesn't come up occasionally but
no clue why. Add thread dumping and state check.
* HBASE-23281: Track meta region changes on masters
This patch adds a simple cache that tracks the meta region replica
locations. It keeps an eye on the region movements so that the
cached locations are not stale.
This information is used for servicing client RPCs for connections
that use master based registry (HBASE-18095). The RPC end points
will be added in a separate patch.

These classifications come of running at various fork counts.. A test
may complete quick if low fork count but if it is accessing disk, it
will run much slower if fork count is high. This edit accommodates
some of this phenomenon.

Get hbase:meta schema from filesystem rather than from hard-coding.
Make it so hbase:meta can be altered. TableState for hbase:meta
was hardcoded ENABLED. Make it dynamic. State is now kept in
current active Master. It is transient so falls back to default
if Master crashes. Add to registry a getMetaTableState
which reads mirrored state from zookeeper (NOT from Master and
defaults ENABLED if no implementation or error fetching state).
hbase:meta schema will be bootstrapped from the filesystem.
Changes to filesystem schema are atomic so we should be ok if
Master fails mid-edit (TBD). Undoes a bunch of guards that
prevented our being able to edit hbase:meta.

If we try to delete too many znodes at once, we'll smack into the
jute.maxbuffer size. Try to prevent that from happening. The dominating
factor of the ZK client request should be the znode side on a delete.

Instead of being an ephemeral state set by hbck, maintenance mode is now
an explicit toggle set by either configuration property or environment
variable. In maintenance mode, master will host system tables and not
assign any user-space tables to RSs. This gives operators the ability to
affect repairs to meta table with fewer moving parts.
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.
Master never left waitForMasterActive because it never checked state of
the clusterUp flag. The test here was aborting regionserver and then
just exiting. The minihbasecluster shutdown sets the cluster down flag
but we were never looking at it so Master thread was staying up.
M hbase-server/src/main/java/org/apache/hadoop/hbase/master/HMaster.java
The tableOnMaster check in waitForMasterActive looks wrong. It was
making it so a 'normal' Master was getting stuck in here. This is not
the place to worry about tablesOnMaster. That is for the balancer to be
concerned with. There is a problem with Master hosting
system-tables-only. After further study, Master can carry regions like a
regionserver but making it so it carries system tables only is tricky
given meta assign happens ahead of all others which means that the
Master needs to have checked-in as a regionserver super early... It
needs work. Punted for now.
M hbase-server/src/main/java/org/apache/hadoop/hbase/master/assignment/AssignmentManager.java
Mostly renaming so lists and maps of region infos have same name as they
have elsewhere in code base and cleaning up confusion that may arise
when we talk of servers-for-system-tables....It is talking about
something else in the code changes here that is other than the normal
understanding. It is about filtering regionservers by their version
numbers so we favor regions with higher version numbers. Needs to go
back up into the balancer.
M hbase-server/src/main/java/org/apache/hadoop/hbase/master/balancer/BaseLoadBalancer.java
It was possible for the Master to be given regions if no regionservers
available (as per the failing unit test in this case).
M hbase-server/src/main/java/org/apache/hadoop/hbase/regionserver/HRegionServer.java
Minor reordering moving the waitForMasterActive later in the initialize
and wrapping each test in a check if we are to keep looping (which
checks cluster status flag).
M hbase-server/src/test/java/org/apache/hadoop/hbase/master/TestAssignmentManagerMetrics.java
This was an old test from the days when Master carried system tables.
Updated test and fixed metrics. Metrics count the hbase:meta along with
the userspace region so upped expected numbers (previously the
hbase:meta was hosted on the master so metrics were not incremented).
M hbase-server/src/test/java/org/apache/hadoop/hbase/master/balancer/TestRegionsOnMasterOptions.java
I took a look at this test again but nope, needs a load of work still to
make it pass.
