-------------------------------------
Summary: Fix Hudi to not write in Parquet legacy format
Key: HUDI-4321
URL: https://issues.apache.org/jira/browse/HUDI-4321
Project: Apache Hudi
Issue Type: Bug
Reporter: Alexey Kudinkin
Currently Hudi have to write in Parquet legacy-format
("spark.sql.parquet.writeLegacyFormat") whenever schema contains Decimals, due
to the fact that it relies on AvroParquetReader which is unable to read
Decimals in the non-legacy format (ie it could only read Decimals encoded as
FIXED_BYTE_ARRAY, and not as INT32/INT64)
This leads to suboptimal storage footprint where for example on some datasets
this could lead to a bloat of 10% or more.
