* Bootstrapping initial support for Metadata Table in Spark Datasource
- Consolidated Avro/Row conversion utilities to center around Spark's AvroDeserializer ; removed duplication
- Bootstrapped HoodieBaseRelation
- Updated HoodieMergeOnReadRDD to be able to handle Metadata Table
- Modified MOR relations to be able to read different Base File formats (Parquet, HFile)
Currently, HadoopFsRelation will use the value of the real partition path as the value of the partition field. However, different from the normal table, Hudi will persist the partition value in the parquet file. And in some cases, it's different between the value of the real partition path and the value of the partition field.
So here we implement BaseFileOnlyViewRelation which lets Hudi manage its own relation.
Refactoring layout optimization (clustering) flow to
- Enable support for linear (lexicographic) ordering as one of the ordering strategies (along w/ Z-order, Hilbert)
- Reconcile Layout Optimization and Clustering configuration to be more congruent
To modify SQL statement for creating hudi table based on an existing hudi path.
From:
```sql
create table hudi_tbl using hudi tblproperties (primaryKey='id', preCombineField='ts', type='cow') partitioned by (pt) location '/path/to/hudi'
```
To:
```sql
create table hudi_tbl using hudi location '/path/to/hudi'
```
* Introduce hudi-spark3-common and hudi-spark2-common modules to place classes that would be reused in different spark versions, also introduce hudi-spark3.1.x to support spark 3.1.x.
* Introduce hudi format under hudi-spark2, hudi-spark3, hudi-spark3.1.x modules and change the hudi format in original hudi-spark module to hudi_v1 format.
* Manually tested on Spark 3.1.2 and Spark 3.2.0 SQL.
* Added a README.md file under hudi-spark-datasource module.
* [HUDI-2909] Handle logical type in TimestampBasedKeyGenerator
Timestampbased key generator was returning diff values for row writer and non row writer path. this patch fixes it and is guarded by a config flag (`hoodie.datasource.write.keygenerator.consistent.logical.timestamp.enabled`)
* [HUDI-2154] Add index key field to HoodieKey
* [HUDI-2157] Add the bucket index and its read/write implemention of Spark engine.
* revert HUDI-2154 add index key field to HoodieKey
* fix all comments and introduce a new tricky way to get index key at runtime
support double insert for bucket index
* revert spark read optimizer based on bucket index
* add the storage layout
* index tag, hash function and add ut
* fix ut
* address partial comments
* Code review feedback
* add layout config and docs
* fix ut
* rename hoodie.layout and rebase master

- Changes the default config of marker type (HoodieWriteConfig.MARKERS_TYPE or hoodie.write.markers.type) from DIRECT to TIMELINE_SERVER_BASED for Spark Engine.
- Adds engine-specific marker type configs: Spark -> TIMELINE_SERVER_BASED, Flink -> DIRECT, Java -> DIRECT.
- Uses DIRECT markers as well for Spark structured streaming due to timeline server only available for the first mini-batch.
- Fixes the marker creation method for non-partitioned table in TimelineServerBasedWriteMarkers.
- Adds the fallback to direct markers even when TIMELINE_SERVER_BASED is configured, in WriteMarkersFactory: when HDFS is used, or embedded timeline server is disabled, the fallback to direct markers happens.
- Fixes the closing of timeline service.
- Fixes tests that depend on markers, mainly by starting the timeline service for each test.
* [HUDI-2101]support z-order for hudi
* Renaming some configs for consistency/simplicity.
* Minor code cleanups
