# Drop-in replacement for the `hive` CLI that routes `hive -f <file>` and
# `hive -e <sql>` through beeline + HiveServer2. This avoids paying the
# ~3-5s JVM cold-start cost per invocation that the real Hive CLI incurs,
# which is by far the dominant cost when loading many tiny DDL scripts.
#
# Everything else is delegated to the real Hive CLI so the shim stays
# transparent for unexpected callers.
#
# Configuration:
#   DORIS_HS2_URL  JDBC URL to HiveServer2 (default: jdbc:hive2://localhost:${HS_PORT:-10000}/default)
#   DORIS_HS2_USER Username passed to beeline (default: root)
