usage: release-build.sh <package|docs|publish-snapshot|publish-release>
Creates build deliverables from a Spark commit.

Top level targets are
  package: Create binary packages and copy them to home.apache
  docs: Build docs and copy them to home.apache
  publish-snapshot: Publish snapshot release to Apache snapshots
  publish-release: Publish a release to Apache release repo

All other inputs are environment variables

GIT_REF - Release tag or commit to build from
SPARK_VERSION - Release identifier used when publishing
SPARK_PACKAGE_VERSION - Release identifier in top level package directory
REMOTE_PARENT_DIR - Parent in which to create doc or release builds.
REMOTE_PARENT_MAX_LENGTH - If set, parent directory will be cleaned to only
 have this number of subdirectories (by deleting old ones). WARNING: This deletes data.

ASF_USERNAME - Username of ASF committer account
ASF_PASSWORD - Password of ASF committer account
ASF_RSA_KEY - RSA private key file for ASF committer account

GPG_KEY - GPG key used to sign release artifacts
GPG_PASSPHRASE - Passphrase for GPG key
