6e28d878b5 [fix](hudi) compatible with hudi spark configuration and support skip merge (#24067)
Fix three bugs:
1. Hudi slice maybe has log files only, so `new Path(filePath)`  will throw errors.
2. Hive column names are lowercase only, so match column names in ignore-case-mode.
3.  Compatible with [Spark Datasource Configs](https://hudi.apache.org/docs/configurations/#Read-Options), so users can add `hoodie.datasource.merge.type=skip_merge` in catalog properties to skip merge logs files.

13c9c41c1f [opt](hudi) reduce the memory usage of avro reader (#23745)
1. Reduce the number of threads reading avro logs and keep the readers in a fixed thread pool.
2. Regularly cleaning the cached resolvers in the thread local map by reflection.

4c4f08f805 [fix](hudi) the required fields are empty if only reading partition columns (#22187)
1. If only read the partition columns, the `JniConnector` will produce empty required fields, so `HudiJniScanner` should read the "_hoodie_record_key" field at least to know how many rows in current hoodie split. Even if the `JniConnector` doesn't read this field, the call of `releaseTable` in `JniConnector` will reclaim the resource.

2. To prevent BE failure and exit, `JniConnector` should call release methods after `HudiJniScanner` is initialized. It should be noted that `VectorTable` is created lazily in `JniScanner`,  so we don't need to reclaim the resource when `HudiJniScanner` is failed to initialize.

## Remaining works
Other jni readers like `paimon` and `maxcompute` may encounter the same problems, the jni reader need to handle this abnormal situation on its own, and currently this fix can only ensure that BE will not exit.

3414d1a61f [fix](hudi) table schema is not the same as parquet schema (#22186)
Upgrade hudi version from 0.13.0 to 0.13.1, and keep the hudi version of jni scanner the same as that of FE.
This may fix the bug of the table schema is not same as parquet schema.

4158253799 [feature](hudi) support hudi time travel in external table (#21739)
Support hudi time travel in external table:
```
select * from hudi_table for time as of '20230712221248';
```
PR(https://github.com/apache/doris/pull/15418) supports to take timestamp or version as the snapshot ID in iceberg, but hudi only has timestamp as the snapshot ID. Therefore, when querying hudi table with `for version as of`, error will be thrown like:
```
ERROR 1105 (HY000): errCode = 2, detailMessage = Hudi table only supports timestamp as snapshot ID
```
The supported formats of timestamp in hudi are: 'yyyy-MM-dd HH:mm:ss[.SSS]' or 'yyyy-MM-dd' or 'yyyyMMddHHmmss[SSS]', which is consistent with the [time-travel-query.](https://hudi.apache.org/docs/quick-start-guide#time-travel-query)

## Partitioning Strategies
Before this PR, hudi's partitions need to be synchronized to hive through [hive-sync-tool](https://hudi.apache.org/docs/syncing_metastore/#hive-sync-tool), or by setting very complex synchronization parameters in [spark conf](https://hudi.apache.org/docs/syncing_metastore/#sync-template). These processes are exceptionally complex and unnecessary, unless you want to query hudi data through hive.

In addition, partitions are changed in time travel. We cannot guarantee the correctness of time travel through partition synchronization.

So this PR directly obtain partitions by reading hudi meta information. Caching and updating table partition information through hudi instant timestamp, and reusing Doris' partition pruning.

0084b9fd9a [fix](hudi) scala can't call Properties.putAll in jdk11 (#21494) 2023-07-05 10:53:09 +08:00
9adbca685a [opt](hudi) use spark bundle to read hudi data (#21260)
Use spark-bundle to read hudi data instead of using hive-bundle to read hudi data.

**Advantage** for using spark-bundle to read hudi data:
1. The performance of spark-bundle is more than twice that of hive-bundle
2. spark-bundle using `UnsafeRow` can reduce data copying and GC time of the jvm
3. spark-bundle support `Time Travel`, `Incremental Read`, and `Schema Change`, these functions can be quickly ported to Doris

**Disadvantage** for using spark-bundle to read hudi data:
1. More dependencies make hudi-dependency.jar very cumbersome(from 138M -> 300M)
2. spark-bundle only provides `RDD` interface and cannot be used directly

current avro reader only support common data type, the complex data types will be supported later.

ef17289925 [feature](jni) add jni metrics and attach to BE profile automatically (#21004)
Add JNI metrics, for example:
```
-  HudiJniScanner:  0ns
  -  FillBlockTime:  31.29ms
  -  GetRecordReaderTime:  1m5s
  -  JavaScanTime:  35s991ms
  -  OpenScannerTime:  1m6s
```
Add three common performance metrics for JNI scanner:
1. `OpenScannerTime`: Time to init and open JNI scanner
2. `JavaScanTime`: Time to scan data and insert into vector table in java side
3. `FillBlockTime`: Time to convert java vector table to c++ block

And support user defined metrics in java side, for example: `OpenScannerTime` is a long time for the open process, we want to determine which sub-process takes too much time, so we add `GetRecordReaderTime` in java side.
The user defined metrics in java side can be attached to BE profile automatically.

923f7edad0 [opt](hudi) using native reader to read the base file with no log file (#20988)
Two optimizations:
1. Insert string bytes directly to remove decoding&encoding process.
2. Use native reader to read the hudi base file if it has no log file. Use `explain` to show how many splits are read natively.

062641e8f8 [fix](hudi) set default class loader for hudi serializer (#20680)
hudi serializer `org.apache.hudi.common.util.SerializationUtils$KryoInstantiator.newKryo` throws error like `java.lang.IllegalArgumentException: classLoader cannot be null`. Set the default class loader for scan thread.
```
public Kryo newKryo() {
    Kryo kryo = new Kryo();
    ...
    // Thread.currentThread().getContextClassLoader() returns null
    kryo.setClassLoader(Thread.currentThread().getContextClassLoader());
    ...
    return kryo;
}

57656b2459 [Enhancement](java-udf) java-udf module split to sub modules (#20185)
The java-udf module has become increasingly large and difficult to manage, making it inconvenient to package and use as needed. It needs to be split into multiple sub-modules, such as : java-commom、java-udf、jdbc-scanner、hudi-scanner、 paimon-scanner.
