What is a Apache Spark?

Apache Spark™ is a fast and general engine for large-scale data processing.
Speed Run programs up to 100x faster than Hadoop MapReduce in memory, or 10x faster on disk.
Ease of Use Write applications quickly in Java, Scala, Python, R.
Generality Combine SQL, streaming, and complex analytics.
Runs Everywhere Spark runs on Hadoop, Mesos, standalone, or in the cloud. It can access diverse data sources including HDFS, Cassandra, HBase, and S3.

Spark runs on Hadoop, Mesos, standalone, or in the cloud. It can access diverse data sources including HDFS, Cassandra, HBase, and S3. You can run Spark using its standalone cluster mode, on EC2, on Hadoop YARN, or on Apache Mesos.

Typical job duties for Apache Spark developer

• Install, configure and maintain enterprise hadoop environment.
• Loading data from different datasets and deciding on which file format is efficient for a task. Hadoop developers source large volumes of data from diverse data platforms into Hadoop platform.
• Understanding the requirements of input to output transformations.
• Hadoop developers spend lot of time in cleaning data as per business requirements using streaming API’s or user defined functions.
• Defining Hadoop Job Flows.
• Build distributed, reliable and scalable data pipelines to ingest and process data in real-time. Hadoop developer deals with fetching impression streams, transaction behaviours, clickstream data and other unstructured data.
• Managing Hadoop jobs using scheduler.
• Reviewing and managing hadoop log files.
• Design and implement column family schemas of Hive and HBase within HDFS.
• Assign schemas and create Hive tables.
• Managing and deploying HBase clusters.
• Develop efficient pig and hive scripts with joins on datasets using various techniques.
• Assess the quality of datasets for a hadoop data lake.
• Apply different HDFS formats and structure like Parquet, Avro, etc. to speed up analytics.
• Build new hadoop clusters
• Maintain the privacy and security of hadoop clusters.
• Fine tune hadoop applications for high performance and throughput.
• Troubleshoot and debug any hadoop ecosystem run time issues.
