Apache Impala: My Insights and Best Practices. Hudi, on the other hand, is designed to work with an underlying Hadoop compatible filesystem (HDFS,S3 or Ceph) and does not have its own fleet of storage servers, instead relying on Apache Spark to do the heavy-lifting. All metadata that Impala needs is stored in the HMS. Apache Kudu A Closer Look at By Andriy Zabavskyy Mar 2017 2. Given Impala is a very common way to access the data stored in Kudu, this capability allows users deploying Impala and Kudu to fully secure the Kudu data in multi-tenant clusters even though Kudu does not yet have native fine-grained authorization of its own. We tried using Apache Impala, Apache Kudu and Apache HBase to meet our enterprise needs, but we ended up with queries taking a lot of time. It implements a distributed architecture based on daemon processes that are responsible for all the aspects of query execution that run on the same machines. Impala provides low latency and high concurrency for BI/analytic queries on Hadoop (not delivered by batch frameworks such as Apache Hive). Also, I want to point out that Kudu is a filesystem, Impala is an in-memory query engine. Ecosystem integration Kudu was specifically built for the Hadoop ecosystem, allowing Apache Spark™, Apache Impala, and MapReduce to process and analyze data natively.
