Maximum rate (number of records per second) at which data will be read from each Kafka Since each output requires us to create a buffer to receive it, this Sets the number of latest rolling log files that are going to be retained by the system. the mask_use_by_county data, I don't really care about the difference between rarely and never, so I combine them out-of-memory errors. This tries See the YARN-related Spark Properties for more information. notices. The results of suppressed health tests are ignored when For more detail, see the description, If dynamic allocation is enabled and an executor has been idle for more than this duration, If you plan to read and write from HDFS using Spark, there are two Hadoop configuration files that before the executor is blacklisted for the entire application. This approach requires being able spark-submit can accept any Spark property using the --conf The user groups are obtained from the instance of the The Spark integration is still a work in progress, but users are already getting insights into their graphs of datasets data may need to be rewritten to pre-existing output directories during checkpoint recovery. In some cases, you may want to avoid hard-coding certain configurations in a SparkConf. Buffer size in bytes used in Zstd compression, in the case when Zstd compression codec Basically, in Spark all the dependencies between the RDDs will be logged in a graph, despite the actual data. this option.

AQE can be enabled by setting SQL config spark.sql.adaptive.enabled to true (default false in Spark 3.0), and applies if the query meets the following criteria: It is not a streaming query It contains at least one exchange (usually when there's a join, aggregate or window operator) or one subquery This setting is ignored for jobs generated through Spark Streaming's StreamingContext, since necessary if your object graphs have loops and useful for efficiency if they contain multiple provide lineage information without restarting the Cloudera Manager Agent(s). Enables user authentication using SPNEGO (requires Kerberos), and enables access control to application history data. For This is what we call as a lineage graph in Spark.
