stack 7df9490d60 HBASE-23899 [Flakey Test] Stabilizations and Debug
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.

hbase-server/src/test/java/org/apache/hadoop/hbase/TestZooKeeper.java
  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.

hbase-server/src/test/java/org/apache/hadoop/hbase/client/TestSplitOrMergeStatus.java
 Move off deprecated APIs.

hbase-server/src/test/java/org/apache/hadoop/hbase/master/balancer/BalancerTestBase.java
 Log when we fail balance check for DEBUG Currently just says 'false'

hbase-server/src/test/java/org/apache/hadoop/hbase/master/procedure/TestSplitWALProcedure.java
 NPEs on way out if setup failed.

hbase-server/src/test/java/org/apache/hadoop/hbase/regionserver/TestCompaction.java
 Add logging when assert fails to help w/ DEBUG

hbase-server/src/test/java/org/apache/hadoop/hbase/regionserver/TestRegionServerAbortTimeout.java
 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.

hbase-zookeeper/src/main/java/org/apache/hadoop/hbase/zookeeper/MiniZooKeeperCluster.java
 Add timeout on socket; was seeing check for zk server getting stuck
 and never timing out (test time out in startup)

hbase-mapreduce/src/test/java/org/apache/hadoop/hbase/snapshot/TestExportSnapshotWithTemporaryDirectory.java
 Write to test data dir instead.
 Be careful about how we make qualified paths.

hbase-mapreduce/src/test/java/org/apache/hadoop/hbase/mapreduce/TestTableInputFormatScanBase.java
 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.
