$ git checkout -b release-<version> <commit-hash>
$ git push origin release-<version>

# Example
$ git checkout -b release-0.23.0-rc c90f66332161b0dea0b09d054ba9e604cea5b6da9abf0a4b105d624ec310273c2bd7f52c1f3ce12a
$ git push origin release-0.23.0-rc

# cd to the top level pinot directory
mvn clean -Ddependency.locations.enabled=false -DskipTests package
cd pinot-distribution/target
unzip pinot-distribution-0.23.0-SNAPSHOT-shaded.jar META-INF/NOTICE
cd ../..
head -6 NOTICE-binary > /tmp/xx
cat pinot-distribution/target/META-INF/NOTICE >> /tmp/xx
cp /tmp/xx NOTICE-binary

git checkout  -- pinot-distribution/pom.xml pom.xml# Revert the changes made temporarily

...

After this step is successfully completed, you should see two extra entries if you issue a git log command on your release branch. One will be a new tag like release-.0.23.0-rc0 and rc2 and the other is a commit to all pom.xml files changing the working release number to the next version. This second commit needs to be eventually cherry-picked to the master, we will get back to it later.

Please refer "Preparing a release" section in http://plc4x.apache.org/developers/release.html to see what actually happens with the command below - has a good explanation along with screenshots, our gitbox url for checking is https://gitbox.apache.org/repos/asf?p=incubator-pinot.git) 

...

$ mvn release:prepare
# Be sure to answer the questions as below (example):
[INFO] Checking dependencies and plugins for snapshots ...
What is the release version for "Pinot"? (org.apache.pinot:pinot) 0.23.0: : 
What is SCM release tag or label for "Pinot"? (org.apache.pinot:pinot) pinot-0.23.0: : release-0.23.0-rc0
What is the new development version for "Pinot"? (org.apache.pinot:pinot) 0.23.1-SNAPSHOT: : 0.34.0-SNAPSHOT

After completion of the command above , you should see two commits on your release branch that look like this (example for 0.23.0 release)

# The commit f8e1980c4160ac7fd2686d9edefab9ac0a825c5b9b2dc20c07dec6cf33df08c4444d996e8202c3ba is just a tag added, and the commit 09efc5af1b88825cbdccf863f5ecef99eb9d85a6e41ae3356c9b6891a179ef3bd674906dcd18408a is the modification of all the pom files to be 0.34.0-SNAPSHOT.
# You will need to cherry-pick this commit into the master branch after the release is done.

You can also verify from https://github.com/apache/incubator-pinot that a new tag has appeared, and that the commit of the pom files shows up.

3. Fill in the release note (cut/paste)
4. Be sure to check the "This is a pre-release" box.
5. Publish the release.
