---------------------------------
Summary: Used fixed/external version from hadoop jars in
hdds/ozone projects
Key: HDDS-702
URL: https://issues.apache.org/jira/browse/HDDS-702
Project: Hadoop Distributed Data Store
Issue Type: New Feature
Reporter: Elek, Marton
Assignee: Elek, Marton
In the current form of the project ozone uses the in-tree snapshot version of
the hadoop (hadoop 3.3.0-SNAPSHOT as of now).
I propose to use a fixed version from the hadoop jars which could be
independent from the in-tree hadoop.
1. With using already released hadoop (such as hadoop-3.1) we can upload the
ozone jar files to the maven repository without pseudo-releasing the hadoop
snapshot dependencies. (In the current form it's not possible without also
uploading a custom, ozone flavour of hadoop-common/hadoop-hdfs)
2. With using fixed version of hadoop the build could be faster and the yetus
builds could be simplified (it's very easy to identify the projects which
should be checked/tested if only the hdds/ozone projects are part of the build:
we can do full build/tests all the time).
After the previous work it's possible to switch to fixed hadoop version,
because:
1) we have no more proto file dependency between hdds and hdfs (HDDS-378, and
previous works by Mukul and Nanda)
2) we don't need to depend on the in-tree hadoop-project-dist (HDDS-447)
