Apache Hive makes multi-structured data accessible to analysts, database administrators, and others without Java programming expertise. Impala uses Hive to read a table's metadata; however, using its own distributed execution engine it makes data processing very fast. Apache Impala enables real-time interactive analysis of the data stored in Hadoop using a native SQL environment. The tpcds__parquet table definition and information can be seen here in Hue 3. Cloudera Impala Details Common Hive SQL and interface Unified metadata and scheduler … Like Apache Drill, Cloudera’s Impala technology seeks to improve interactive query response time for Hadoop users. So the very first benefit of using Impala is the super fast access of data from HDFS. Apache Hive makes multi-structured data accessible to analysts, database administrators, and others without Java programming expertise. Impala uses the same metadata, SQL syntax (Hive SQL), ODBC driver, and user interface (Hue Beeswax) as Apache Hive, providing a familiar and unified platform for batch-oriented or real-time queries. I've already invalidated metadata for that table but cannot see any of the existing records. In Hue, we see the tpcds_parquet database in the impala/hive metastore 2.
