Only Aggressive Elephants are Fast Elephants

Summary: HAIL extends HDFS upload to build per-block clustered indexes on every replica, enabling fast selective MapReduce access. Aggressive indexing yields up to 60% faster uploads (default three replicas) and up to 68x faster MapReduce queries, demonstrated across six large clusters. (summarized by gpt-5-nano on Feb 09 2026)
