Deploys Apache Hive 3.1.3 (Derby metastore + external table over the HDFS
historical CSV, MapReduce exec) on the Hadoop master, so the engine comparison
shows a REAL measured Hive latency (~5.2s) next to live Trino (~0.3s); Impala
stays clearly-labelled representative. The API re-measures Hive over SSH on a
30-min TTL (cached + persisted, with a committed seed). Adds filters
(year/region/category/channel), a region×category heatmap, Trino exec stats,
and a "where is this data read from" lineage panel (Trino->S3/Iceberg/Parquet
with snapshot+files, Hive->HDFS/CSV with namenode+files). Mounts host SSH key
read-only into the api container for the live Hive benchmark.
Talisman forced Secure on the session cookie while Superset is served over
plain HTTP, so browsers never returned the cookie and every login failed CSRF
validation ("CSRF session token is missing"). Set session_cookie_secure=False
(+ SESSION_COOKIE_SECURE/WTF_CSRF_SSL_STRICT). Also rename S3 lakehouse prefix
iceberg-warehouse -> hadoop (Trino iceberg.hadoop.historical_sales) and repoint
the Superset dataset. Adds sanitized infra backup scripts.
