Restore behavior from before HBASE-21789 (hbase-2.2.0) where we convert
all exceptions to IOEs, even RuntimeExceptions. Actual fix is this change (in case
obscured by doc and lambda simplification):
} catch (Throwable e) {
- Throwables.propagateIfPossible(e, IOException.class);
+ // Throw if an IOE else wrap in an IOE EVEN IF IT IS a RuntimeException (e.g.
+ // a RejectedExecutionException because the hosting exception is shutting down.
+ // This is old behavior worth reexamining. Procedures doing merge or split
+ // currently don't handle RuntimeExceptions coming up out of meta table edits.
+ // Would have to work on this at least. See HBASE-23904.
+ Throwables.throwIfInstanceOf(e, IOException.class);
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).

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.

A general problem is that zk cluster doesn't come up occasionally but

Master rpc server end point doesn't bind to localhost's
IP address by default. Instead, it looks up the hostname and
binds to the endpoint to which it resolves. MasterRegistry should
do the same when building the default server end point to talk to.

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.

Change its behavior so it will only look in hbase:meta
if the call to the super class turns up zero references.
Only then will it search hbase:meta for references to
'Unknown Servers'. Normal operation where we read Master
context is usual and sufficient. The scan of hbase:meta
is only for case where Master state has been corrupted
and we need to clear out 'Unknown Servers'.

Have the existing scheduleRecoveries launch a new HBCKSCP
instead of SCP. It gets regions to recover from Master
in-memory context AND from a scan of hbase:meta. This
new HBCKSCP is For processing 'Unknown Servers', servers that
are 'dead' and purged but still have references in
hbase:meta. Rare occurance but needs tooling to address.
Later have catalogjanitor take care of these deviations
between Master in-memory and hbase:meta content (usually
because of overdriven cluster with failed RPCs to hbase:meta,
etc)
Changed expireServers in ServerManager so could pass in
custom reaction to expired server.... This is how we
run our custom HBCKSCP while keeping all other aspects
of expiring services (rather than try replicate it
externally).
Includes the following, incorporating HBASE-20439 and HBASE-20440, too.
1)
HBASE-18133 Decrease quota reaction latency by HBase
Certain operations in HBase are known to directly affect
the utilization of tables on HDFS. When these actions
occur, we can circumvent the normal path and notify the
Master directly. This results in a much faster response to
changes in HDFS usage.
This requires FS scanning by the RS to be decoupled from
the reporting of sizes to the Master. An API inside each
RS is made so that any operation can hook into this call
in the face of other operations (e.g. compaction, flush,
bulk load).
2)
HBASE-18135 Implement mechanism for RegionServers to report file archival for space quotas
This de-couples the snapshot size calculation from the
SpaceQuotaObserverChore into another API which both the periodically
invoked Master chore and the Master service endpoint can invoke. This
allows for multiple sources of snapshot size to reported (from the
multiple sources we have in HBase).
When a file is archived, snapshot sizes can be more quickly realized and
the Master can still perform periodical computations of the total
snapshot size to account for any delayed/missing/lost file archival RPCs.
3)
HBASE-20531 RS may throw NPE when close meta regions in shutdown procedure.
