Why Impala is faster than Hive?
Your analysts will get their answer way faster using Impala, although unlike Hive, Impala is not fault-tolerance. Impala is faster than Hive because it’s a whole different engine and Hive is over MapReduce (which is very slow due to its too many disk I/O operations).
Is Impala a DB?
Impala is not a Database. Impala is a MPP (Massive Parallel Processing) SQL query Engine. It is an interface of SQL on top of HDFS structure. Impala provides fast, interactive SQL queries directly on your Apache Hadoop data stored in HDFS, HBase, or the Amazon Simple Storage Service (S3).
Is Impala a fault tolerance?
But on the whole, Impala is very fault-tolerant. All Impalads have a peer-to-peer structure. Users can submit queries to any Impalad. If an Impalad fails, all queries running on the above will fail, but the user can resubmit the query to be executed by other Impalads, without affecting the service.
