Summary: Add support for lz4 in parquet
Key: IMPALA-8617
URL: https://issues.apache.org/jira/browse/IMPALA-8617
Project: IMPALA
Issue Type: Improvement
Components: Backend
Reporter: Abhishek Rawat
Assignee: Abhishek Rawat
Hadoop uses a native block format for LZ4 (same as parquet-mr api) which is
incompatible with LZ4 block format.
As a result Parquet/LZ4 could have different block formats.
The parquet-cpp api (now Apache Arrow) uses parquet frame format, which is also
incompatible with Parquet block format.
The current decision is to use a format compatible with Hive, Spark and
parquet-mr.
