## What changes were proposed in this pull request? This PR targets to document `-I` option from Spark 2.4.x (previously `-i` option until Spark 2.3.x). After we upgraded Scala to 2.11.12, `-i` option (`:load`) was replaced to `-I`(SI-7898). Existing `-i` became `:paste` which does not respect Spark's implicit import (for instance `toDF`, symbol as column, etc.). Therefore, `-i` option does not correctly from Spark 2.4.x and it's not documented. I checked other Scala REPL options but looks not applicable or working from quick tests. This PR only targets to document `-I` for now. ## How was this patch tested? Manually tested. **Mac:** ```bash $ ./bin/spark-shell --help Usage: ./bin/spark-shell [options] Scala REPL options: -I <file> preload <file>, enforcing line-by-line interpretation Options: --master MASTER_URL spark://host:port, mesos://host:port, yarn, k8s://https://host:port, or local (Default: local[*]). --deploy-mode DEPLOY_MODE Whether to launch the driver program locally ("client") or on one of the worker machines inside the cluster ("cluster") (Default: client). ... ``` **Windows:** ```cmd C:\...\spark>.\bin\spark-shell --help Usage: .\bin\spark-shell.cmd [options] Scala REPL options: -I <file> preload <file>, enforcing line-by-line interpretation Options: --master MASTER_URL spark://host:port, mesos://host:port, yarn, k8s://https://host:port, or local (Default: local[*]). --deploy-mode DEPLOY_MODE Whether to launch the driver program locally ("client") or on one of the worker machines inside the cluster ("cluster") (Default: client). ... ``` Closes #22919 from HyukjinKwon/SPARK-25906.
