Revert "HBASE-25032 Wait for region server to become online before adding it to online servers in Master (#2771)"
This reverts commit 5d7e2f71f74bcdb7cf1d530372fb3d0ffd03d6fd.
In CatalogJanitor we schedule GCRegionProcedure to clean up both
filesystem and in-memory state after a split, and
GCMultipleMergedRegionsProcedure to do the same for merges. Both of these
procedures clean up in-memory state, but CatalogJanitor also does this
redundantly just after scheduling the procedures. The cleanup should be
done in only one place. Presumably we are using the procedures to do it in
a principled way. Remove the redundancy in CatalogJanitor and fix any
follow on issues, like test failures.

Processing of the RS report happens asynchronously from other activities
which can mutate region state. For example, a split procedure may already
be running. A split procedure cannot succeed if the parent region is no
longer open, so we can ignore it in that case.
Note that submitting more than one split procedure for a given region is
harmless -- the split is fenced in the procedure handling -- but it would
be noisy in the logs. Only one procedure can succeed. The other
procedure(s) would abort during initialization and report failure with
WARN level logging.

RegionStates#getAssignmentsForBalancer is used by the HMaster to
collect all regions of interest to the balancer for the next chore
iteration. We check if a table is in disabled state to exclude
regions that will not be of interest (because disabled regions are
or will be offline) or are in a state where they shouldn't be
mutated (like SPLITTING). The current checks are not actually
comprehensive.
Filter out regions not in OPEN or OPENING state when building the
set of interesting regions for the balancer to consider. Only
regions open (or opening) on the cluster are of interest to
balancing calculations for the current iteration. Regions in all
other states can be expected to not be of interest – either offline
(OFFLINE, or FAILED_*), not subject to balancer decisions now
(SPLITTING, SPLITTING_NEW, MERGING, MERGING_NEW), or will be
offline shortly (CLOSING) – until at least the next chore
iteration.
Add TRACE level logging.

We claim in a WARN level log line to be "Playing-it-safe skipping merge/
split gc'ing of regions from hbase:meta while regions-in-transition (RIT)"
but do not actually skip because of a missing return. Remove the warning.

There are code paths in which we throw non-IOExceptions when
initializing a WAL reader. However, we only close the InputStream to the
WAL filesystem when the exception is an IOException. Close it if it is
open in all cases.

The issue is that FileInputStream is created with try-with-resources, so its close() is called right after the try sentence.
FileInputStream is a finalize class, when this object is garbage collected, its close() is called again.
To avoid this double-free resources, add guard against it.

Don't have every handler update regionserver metrics on each
scan#nextRaw; instead, do a batch update just before Scan
returns. Otherwise, all running handlers end up contending
on metrics update.

Update of regionserver metrics counters moved out to caller where
can be done as a batch update instead of per-next.
