Dataproc - July 12th, 2021 [Change]

## Change For 2.0+ image clusters, the `dataproc:dataproc.master.custom.init.actions.mode` [cluster property](https://cloud.google.com/dataproc/docs/concepts/configuring-clusters/cluster-properties#service%5Fproperties) can be set to `RUN_AFTER_SERVICES` to run initialization actions on the master after HDFS and any services that depend on HDFS are initialized. Examples of HDFS-dependent services include: HBase, Hive Server2, Ranger, Solr, and the Spark and MapReduce history servers. Default: `RUN_BEFORE_SERVICES`.
