As puublished in Apache Drill documentation, it supports full ANSI SQL 2003. My question here is how exactly Drill can execute queries in which row level data updated or deleted on HDFS/HIVE ? AS we all know its not possible to modify data in HDFS. 1 more request, can anyone please create a tag for 'Apache Drill' as it requires high credentials.

Drill 支持的不仅仅是 HDFS 文件系统。S3、本地 Linux 文件系统、NTFS、MapR-FS 以及 HDFS。

目前，Drill 不允许单个记录更新，但我认为该功能已在路线图上。
