> h2. Problem
> The spark-sql CLI (bin/spark-sql -> SparkSQLCLIDriver, in sql/hive-thriftserver) runs only against a local, in-process SparkSession. Unlike spark-shell (SPARK-48936) and spark-submit (SPARK-48960), it cannot target a Spark Connect server; there is no "spark-sql --remote sc://...". It is the last interactive entry point without Connect support and the only one still requiring a local Catalyst driver and the Hive Thrift Server module.
> h2. Approach
> Add a new SparkConnectSQLCLIDriver in sql/connect/client/jvm, selected when --remote / spark.api.mode=connect is set (the same dispatch spark-shell uses), mirroring ConnectRepl (SPARK-48936). It builds a remote SparkSession via the Connect JVM client, executes statements with spark.sql(...), and renders tab-separated output client-side. The existing SparkSQLCLIDriver (Catalyst / hive-thriftserver-coupled) is unchanged and remains the default; no existing public API changes and no dependency on sql/hive-thriftserver.
> h2. Scope (MVP first)
> MVP: remote session + -e / -f + an interactive loop + basic tabular output. Follow-ups: full hiveResultString output parity (types, nulls, complex/nested, timestamps), the remaining CLI flags, and init files.
> Relates to SPARK-49194.
