new 4282d890d8 [MINOR] Properly registering target classes w/ Kryo (#7026)
4282d890d8 is described below
commit 4282d890d877030d8e883ee576628962df2b629e
Author: Alexey Kudinkin <al...@gmail.com>
AuthorDate: Thu Oct 27 18:03:54 2022 -0700
[MINOR] Properly registering target classes w/ Kryo (#7026)
* Added `HoodieKryoRegistrar` registering necessary Hudi's classes w/ Kryo to make their serialization more efficient (by serializing just the class id, in-liue the fully qualified class-name)
* Redirected Kryo registration to `HoodieKryoRegistrar`
* Registered additional classes likely to be serialized by Kryo
* Updated tests
* Fixed serialization of Avro's `Utf8` to serialize just the bytes
* Added tests
* Added custom `AvroUtf8Serializer`;
Tidying up
* Extracted `HoodieCommonKryoRegistrar` to leverage in `SerializationUtils`
* `HoodieKryoRegistrar` > `HoodieSparkKryoRegistrar`;
Rebased `HoodieSparkKryoRegistrar` onto `HoodieCommonKryoRegistrar`
* `lint`
* Fixing compilation for Spark 2.x
* Disabling flaky test
