* [HUDI-995] Use HoodieTestTable in more classes
Migrate test data prep logic in
- TestStatsCommand
- TestHoodieROTablePathFilter
Re-implement methods for create new commit times in HoodieTestUtils and HoodieClientTestHarness
- Move relevant APIs to HoodieTestTable
- Migrate usages
After changing to HoodieTestTable APIs, removed unused deprecated APIs in HoodieTestUtils

- Migrate writeParquetFiles() in HoodieClientTestUtils to HoodieWriteableTestTable
- Adopt HoodieWrittableTestTable for test cases in
- ITTestRepairsCommand.java
- TestHoodieIndex.java
- TestHoodieKeyLocationFetchHandle.java
- TestHoodieGlobalBloomIndex.java
- TestHoodieBloomIndex.java
- Renamed HoodieTestTable and FileCreateUtils APIs
- dataFile changed to baseFile
- Adding ability to use native spark row writing for bulk_insert
- Controlled by `ENABLE_ROW_WRITER_OPT_KEY` datasource write option
- Introduced KeyGeneratorInterface in hudi-client, moved KeyGenerator back to hudi-spark
- Simplified the new API additions to just two new methods : getRecordKey(row), getPartitionPath(row)
- Fixed all built-in key generators with new APIs
- Made the field position map lazily created upon the first call to row based apis
- Implemented native row based key generators for CustomKeyGenerator
- Fixed all the tests, with these new APIs

- This pull request adds upgrade/downgrade infra for smooth transition from list based rollback to marker based rollback*
- A new property called hoodie.table.version is added to hoodie.properties file as part of this. Whenever hoodie is launched with newer table version i.e 1(or moving from pre 0.6.0 to 0.6.0), an upgrade step will be executed automatically to adhere to marker based rollback.*
- This automatic upgrade step will happen just once per dataset as the hoodie.table.version will be updated in property file after upgrade is completed once*
- Similarly, a command line tool for Downgrading is added if incase some user wants to downgrade hoodie from table version 1 to 0 or move from hoodie 0.6.0 to pre 0.6.0*
- *Added UpgradeDowngrade to assist in upgrading or downgrading hoodie table*
- *Added Interfaces for upgrade and downgrade and concrete implementations for upgrading from 0 to 1 and downgrading from 1 to 0.*
- *Made some changes to ListingBasedRollbackHelper to expose just rollback stats w/o performing actual rollback, which will be consumed by Upgrade infra*
- Reworking failure handling for upgrade/downgrade
- Changed tests accordingly, added one test around left over cleanup
- New tables now write table version into hoodie.properties
- Clean up code naming, abstractions.

* [HUDI-839] Introducing rollback strategy using marker files
- Adds a new mechanism for rollbacks where it's based on the marker files generated during the write
- Consequently, marker file/dir deletion now happens post commit, instead of during finalize
- Marker files are also generated for AppendHandle, making it consistent throughout the write path
- Until upgrade-downgrade mechanism can upgrade non-marker based inflight writes to marker based, this should only be turned on for new datasets.
- Added marker dir deletion after successful commit/rollback, individual files are not deleted during finalize
- Fail safe for deleting marker directories, now during timeline archival process
- Added check to ensure completed instants are not rolled back using marker based strategy. This will be incorrect
- Reworked tests to rollback inflight instants, instead of completed instants whenever necessary
- Added an unit test for MarkerBasedRollbackStrategy

- use codecov flags for each module to report coverage
- parallelize CI jobs for shorter time
- add a testcase for MetricsReporterFactory (to trigger codecov comment)
Notable changes:
1. HoodieFileWriter and HoodieFileReader abstractions for writer/reader side of a base file format
2. HoodieDataBlock abstraction for creation specific data blocks for base file formats. (e.g. Parquet has HoodieAvroDataBlock)
3. All hardocded references to Parquet / Parquet based classes have been abstracted to call methods which accept a base file format
4. HiveSyncTool accepts the base file format as a CLI parameter
5. HoodieDeltaStreamer accepts the base file format as a CLI parameter
6. HoodieSparkSqlWriter accepts the base file format as a parameter
- Savepoint and compaction classes moved to table.action.* packages
- HoodieWriteClient#savepoint(...) returns void
- Renamed HoodieCommitArchiveLog -> HoodieTimelineArchiveLog
- Fixed tests to take into account the additional validation done
- Moved helper code into CompactHelpers and SavepointHelpers
HUDI specific validation of schema evolution should ensure that a newer schema can be used for the dataset by checking that the data written using the old schema can be read using the new schema.
Code changes:
1. Added a new config in HoodieWriteConfig to enable schema validation check (disabled by default)
2. Moved code that reads schema from base/log files into hudi-common from hudi-hive-sync
3. Added writerSchema to the extraMetadata of compaction commits in MOR table. This is same as that for commits on COW table.
Testing changes:
4. Extended TestHoodieClientBase to add insertBatch API which allows inserting a new batch of unique records into a HUDI table
5. Added a unit test to verify schema evolution for both COW and MOR tables.
6. Added unit tests for schema compatiblity checks.
- rollback() and restore() table level APIs introduced
- Restore is implemented by wrapping calls to rollback executor
- Existing tests transparently cover this, since its just a refactor
This is to ensure that tests will execute all code paths, even the ones
written under DEBUG log levels. This will improve coverage as well as
ensure there are no surprised when DEBUG log level is enabled in
production.
- Brings more order and cohesion to the classes in hudi-common
- Utils classes related to a particular concept (avro, timeline,...) are placed near to the package
- common.fs package now contains all the filesystem level classes including wrapper filesystem
- bloom.filter package renamed to just bloom
- config package contains classes that help store properties
- common.fs.inline package contains all the inline filesystem classes/impl
- common.table.timeline now consolidates all timeline related classes
- common.table.view consolidates all the classes related to filesystem view metadata
- common.table.timeline.versioning contains all classes related to versioning of timeline
- Fix few unit tests as a result
- Moved the test packages around to match the source file move
- Rename AvroUtils to TimelineMetadataUtils & minor fixes/typos
