When true, Spark does not respect the target size specified by 'spark.sql.adaptive.advisoryPartitionSizeInBytes' (default 64MB) when coalescing contiguous shuffle partitions, but adaptively calculate the target size according to the default parallelism of the Spark cluster. Configures the maximum size in bytes per partition that can be allowed to build local hash map. When dynamic allocation is disabled, it allows users to specify different task resource requirements at stage level, and this is supported on Standalone cluster right now. Asking for help, clarification, or responding to other answers. the event of executor failure. The default SO_BACKLOG is NetUtils.SOMAXCONN.
