## current the limit is 650MB. The release manager have to remove spark binary,
## so Kylin end user should execute this script to download and unzip Spark binary.
## After remove spark binary, Kylin binary is 476MB in 2023/03/09.
## Check details at https://issues.apache.org/jira/browse/INFRA-24053
