--------------------------------------
Summary: RocksDB included in client libs doubles shaded jar size
Key: HDDS-8079
URL: https://issues.apache.org/jira/browse/HDDS-8079
Project: Apache Ozone
Issue Type: Bug
Components: build
Affects Versions: 1.4.0
Reporter: Attila Doroszlai
HDDS-7905 moved the Managed RocksDB classes from {{hadoop-hdds/framework}} to
{{hadoop-hdds/common}} to be able to use them from
{{rocksdb-checkpoint-differ}}.
{{common}} is shared between client and server components. Thus RocksDB
library ends up in shaded FS jars. Since {{rocksdbjni-7.7.3.jar}} is 56MB, it
almost doubles shaded jar sizes:
{code:title=before}
60M share/ozone/lib/ozone-filesystem-hadoop3-1.4.0-SNAPSHOT.jar
{code}
{code:title=after}
115M share/ozone/lib/ozone-filesystem-hadoop3-1.4.0-SNAPSHOT.jar
{code}
Please create a separate module for RocksDB-related stuff, and make
{{hdds-framework}} and {{rocksdb-checkpoint-differ}} both depend on it.
