WAL storage can be expensive, especially if the cell values
represented in the edits are large, consisting of blobs or
significant lengths of text. Such WALs might need to be kept around
for a fairly long time to satisfy replication constraints on a space
limited (or space-contended) filesystem.
We have a custom dictionary compression scheme for cell metadata that
is engaged when WAL compression is enabled in site configuration.
This is fine for that application, where we can expect the universe
of values and their lengths in the custom dictionaries to be
constrained. For arbitrary cell values it is better to use one of the
available compression codecs, which are suitable for arbitrary albeit
compressible data.

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.

There are code paths in which we throw non-IOExceptions when

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.

ProtobufLogReader#readNext may be called by code that attempts to advance
the reader but does not necessarily expect to succeed, for example
WALEntryStream#tryAdvanceEntry. Much of the logging in this method is
at TRACE level. Other logging at WARN level will be frequently emitted, as
often as several per minute, and this will cause false positive assessment
from operators that they are experiencing a bug. Fix the mixed intent with
respect to log levels in readNext. Log at only DEBUG level or below.
