Akshat Mathur updated HIVE-27475:
---------------------------------
Description:
It was needed to shade a version of zstd-jni that is compatible with parquet in
hive-ql after upgrading parquet version dowstream, otherwise Tez couldn't work
with parquet and zstd encryption. Parquet and kafka-client both use zstd-jni.
In hive-ql, zstd-jni is coming as a transitive dependency from kafka-client.
The zstd-jni version in kafka-client 2.5.0 was not compatible with parquet, so
in [PR-4082|[http://example.com|https://github.com/apache/hive/pull/4082]]
kafka-client was upgraded to latest version which used zstd-jni version close
to the version in parquet.
While the upgrade fixed the zstd-ini issue, It introduced multiple
compatibility issue in the Kafka-handler.
With the recent refactor in [HIVE-27402|http://example.com], Kafka-client
dependency was moved out of hive-ql, Which fixed the original zstd-ini
issue.(confirmed by [~difin])
Hence , It makes more sense to downgrade kafka versions back to 2.5.0,
stabalize kafka-handler, enable test and then upgrade.
