Apply gzip, snappy, bzip2, and lz4 compression when ingesting data into hdfs. Compare splittability, speed, and storage to choose the right codec for mapreduce and sqoop workflows.
Copy and paste the beeline command to connect to the hive shell, using your username and cluster name, then execute hive queries on google cloud.
Enable data consolidation with Apache Flume by ingesting from multiple sources—netcat, spool directory, and X source—and dumping to a single Avro sink connected to HDFS.
Explore hive analytics with sql-like queries using group by, order by, and aggregates on city data, powered by MapReduce, and apply having, case statements, and min, max, sum, avg.
Learn to create a hive table stored as parquet from an existing table, load data with a select statement, and verify parquet format, schema, and HDFS location using describe format.
Master altering tables with the alter command, adding new columns, renaming columns and tables, setting properties, changing file formats, and updating table locations to reflect new schemas.
Explore distributed storage basics, including how data splits into 128 chunks that form HDFS blocks, distributed across multiple machines and managed by name nodes and data nodes.
explain how the driver process analyzes code for syntax, builds logical and physical plans, and assigns tasks to executors, enabling four parallel tracks.
