* HBASE-25824 IntegrationTestLoadCommonCrawl
This integration test loads successful resource retrieval records from
the Common Crawl (https://commoncrawl.org/) public dataset into an HBase
table and writes records that can be used to later verify the presence
and integrity of those records.
Run like:
./bin/hbase org.apache.hadoop.hbase.test.IntegrationTestLoadCommonCrawl \
-Dfs.s3n.awsAccessKeyId=<AWS access key> \
-Dfs.s3n.awsSecretAccessKey=<AWS secret key> \
/path/to/test-CC-MAIN-2021-10-warc.paths.gz \
/path/to/tmp/warc-loader-output
Access to the Common Crawl dataset in S3 is made available to anyone by
Amazon AWS, but Hadoop's S3N filesystem still requires valid access
credentials to initialize.
The input path can either specify a directory or a file. The file may
optionally be compressed with gzip. If a directory, the loader expects
the directory to contain one or more WARC files from the Common Crawl
dataset. If a file, the loader expects a list of Hadoop S3N URIs which
point to S3 locations for one or more WARC files from the Common Crawl
dataset, one URI per line. Lines should be terminated with the UNIX line
terminator.
Included in hbase-it/src/test/resources/CC-MAIN-2021-10-warc.paths.gz
is a list of all WARC files comprising the Q1 2021 crawl archive. There
are 64,000 WARC files in this data set, each containing ~1GB of gzipped
data. The WARC files contain several record types, such as metadata,
request, and response, but we only load the response record types. If
the HBase table schema does not specify compression (by default) there
is roughly a 10x expansion. Loading the full crawl archive results in a
table approximately 640 TB in size.
The hadoop-aws jar will be needed at runtime to instantiate the S3N
filesystem. Use the -files ToolRunner argument to add it.
You can also split the Loader and Verify stages:
Load with:
./bin/hbase 'org.apache.hadoop.hbase.test.IntegrationTestLoadCommonCrawl$Loader' \
-files /path/to/hadoop-aws.jar \
-Dfs.s3n.awsAccessKeyId=<AWS access key> \
-Dfs.s3n.awsSecretAccessKey=<AWS secret key> \
/path/to/test-CC-MAIN-2021-10-warc.paths.gz \
/path/to/tmp/warc-loader-output
Verify with:
./bin/hbase 'org.apache.hadoop.hbase.test.IntegrationTestLoadCommonCrawl$Verify' \
/path/to/tmp/warc-loader-output

IntegrationTestImportTsv is generating HFiles under the working directory of the
current hdfs user executing the tool, before bulkloading it into HBase.
Assuming you encrypt the HBase root directory within HDFS (using HDFS
Transparent Encryption), you can bulkload HFiles only if they sit in the same
encryption zone in HDFS as the HBase root directory itself.
When IntegrationTestImportTsv is executed against a real distributed cluster
and the working directory of the current user (e.g. /user/hbase) is not in the
same encryption zone as the HBase root directory (e.g. /hbase/data) then you
will get an exception:
```
ERROR org.apache.hadoop.hbase.regionserver.HRegion: There was a partial failure
due to IO when attempting to load d :

can't be moved into an encryption zone.
```
In this commit I make it configurable where the IntegrationTestImportTsv
generates the HFiles.

Sometimes running chaos monkey, I've found that we lose accounting of
region servers. I've taken to a manual process of checking the
reported list against a known reference. It occurs to me that
ChaosMonkey has a known reference, and it can do this accounting for
me.

Running `ServerKillingChaosMonkey` via `RESTApiClusterManager` for any
duration of time slowly leaks region servers. I see failures on the
RESTApi side go unreported on the ChaosMonkey side. It seems like
`RuntimeException`s are being thrown and lost.
`PolicyBasedChaosMonkey` uses a primitive means of thread management
anyway. Update to use a thread pool, thread groups, and an
uncaughtExceptionHandler.

* sometimes API calls return with null/empty response bodies. thus,
wrap all API calls in a retry loop.
* calls that submit work in the form of "commands" now retrieve the
commandId from successful command submission, and track completion
of that command before returning control to calling context.
* model CM's process state and use that model to guide state
transitions more intelligently. this guards against, for example,
the start command failing with an error message like "Role must be
stopped".
* improvements to logging levels, avoid spamming logs with the
side-effects of retries at this and higher contexts.
* include references to API documentation, such as it is.

`RollingBatchRestartRsAction` doesn't handle failure cases when
tracking its list of dead servers. The original author believed that a
failure to restart would result in a retry. However, by removing the
dead server from the failed list, that state is lost, and retry never
occurs. Because this action doesn't ever look back to the current
state of the cluster, relying only on its local state for the current
action invocation, it never realizes the abandoned server is still
dead. Instead, be more careful to only remove the dead server from the
list when the `startRs` invocation claims to have been successful.

simple unit test covering a very limited selection of the overall API
surface area, just enough to ensure deserialization works.

- MOB compaction is now handled in-line with per-region compaction on region
servers
- regions with mob data store per-hfile metadata about which mob hfiles are
referenced
- admin requested major compaction will also rewrite MOB files; periodic RS
initiated major compaction will not
- periodically a chore in the master will initiate a major compaction that
will rewrite MOB values to ensure it happens. controlled by
'hbase.mob.compaction.chore.period'. default is weekly
- control how many RS the chore requests major compaction on in parallel
with 'hbase.mob.major.compaction.region.batch.size'. default is as
parallel as possible.
- periodic chore in master will scan backing hfiles from regions to get the
set of referenced mob hfiles and archive those that are no longer
referenced. control period with 'hbase.master.mob.cleaner.period'
- Optionally, RS that are compacting mob files can limit write
amplification by not rewriting values from mob hfiles over a certain size
limit. opt-in by setting 'hbase.mob.compaction.type' to 'optimized'.
control threshold by 'hbase.mob.compactions.max.file.size'.
default is 1GiB
- Should smoothly integrate with existing MOB users via rolling upgrade.
will delay old MOB file cleanup until per-region compaction has managed
to compact each region at least once so that used mob hfile metadata can
be gathered.
We have this nice description in the java doc on ITBLL but it's
unformatted and thus illegible. Add some formatting so that it can be
