[PR] [AURON #2308] fix: capture nativeSortExecNode before RDD creation to prevent NPE in NativeShuffleExchangeBase [auron]

["Deegue (via GitHub)" <gi...@apache.org>]

Deegue opened a new pull request, #2310:
URL: https://github.com/apache/auron/pull/2310

   # Which issue does this PR close?
   
   Closes #2308
   
   # Rationale for this change
   
   Capture nativeSortExecNode (and nativeHashExprs) as local vals before creating the NativeRDD closure. Without this, the closure references `this` which can be null at task execution time when the SparkPlan tree has been cleared, causing a NullPointerException during RangePartitioning shuffle writes.
   
   # What changes are included in this PR?
   capture `this.nativeSortExecNode`
   
   # Are there any user-facing changes?
   No.
   
   # How was this patch tested?
   UTs.
