While it is simple to enable shuffle tracking, the way to set up the external shuffle service varies across cluster managers: Without deleting shuffle files written by them (more detail describedīelow). The purpose of the external shuffle service or the shuffle tracking or the ShuffleDriverComponents supports reliable storage is to allow executors to be removed your application must configure .plugin.class to use a custom ShuffleDataIO who’s ShuffleDriverComponents supports reliable storage.your application must set both and .enabled to true, or.your application must set to true, or.your application must set to true after you set up an external shuffle service on each worker node in the same cluster, or. ![]() Regardless of which approach you choose, your application must set to true first, additionally, There are several ways for using this feature. When you want to use dynamic allocation in standalone mode, you are recommended to explicitly set cores for each executor before the issue SPARK-30299 got fixed. In this case, when dynamic allocation enabled, spark will possibly acquire much more executors than expected.
