(record) in the partition, which logically occupies the space of the other part of the memory within the JVM heap, and the different record spaces of the same Partition are not contiguous.After the RDD is cached to storage memory, the Partition is converted to Block,record to occupy a contiguous space in the heap or out-of-heap storage memory. The process of converting partition from discontinuous storage spaces to contiguous storage spaces, which spark calls "unwinding" (

/shufflememorymanager.scala). In a sense, spark uses this part of memory for the shuffle phase to invoke other specific tasks. When shuffle is executed, sometimes you need to sort the data. In the sort phase, you usually also need a buffer-like cache to store the sorted data (remember, you can't modify the data already in the LRU cache, because that data might be reused). Therefore, a certain amount of RAM is required to store data blocks that have been sorted. If you don't have enough memory to

The Vim plugin is a. Vim script file that defines functions, mappings, grammar rules, and commands that can be used to manipulate windows, buffers, and rows. Typically a plug-in contains command definitions and event hooks. When using Python to write Vim plug-ins, the outside of the function is written using VIML, although Viml learned quickly, but Python more flexible, such as the use of Urllib/httplib/simplejson to access some WEB services, which is why many need to visit The plugin for WEB se
