   The patch fixed "nothing provides python needed by ycsb-0.12.0-1.el8.noarch" error on deployment on my CentOS 8.
   
   I got following error on smoke-test even with the patch applied.
   ```
   TestYcsbSmoke > BasicDBTest STANDARD_OUT
       Failed command: ycsb load basic -P /usr/lib/ycsb/workloads/workloada -p recordcount=500000 -s > load_basic.dat
           error code: 127
           stdout: []
           stderr: [env: 'python': No such file or directory]
   
   Gradle Test Executor 2 finished executing tests.

   ```
   
   It looks like `python` is used in the scripts of ycsb. We may need to create symlink same as done for toolchain manifest:
