jinxing64 opened a new pull request #1294: [CALCITE-3167] Remove redundant 
overriding methods of equals&hashcode in EnumerableTableScan.java
URL: https://github.com/apache/calcite/pull/1294
 
 
   ## What changes were proposed in this pull request?
   
   In current code of EnumerableTableScan.java, methods of equals&hashCode are 
overrided for matching of EnumerableTableScans.
   While after optimizing with the same HEP planner, EnumerableTableScans from 
two plans but with the same digest will the share the same Java object.

   I think it's ok to remove the redundant overriding methods in 
EnumerableTableScan.java
   
   This is a minor change and I dig into this for the curiosity that 
EnumerableTableScan have the overriding methods but LogicalTableScan doesn't.
   
   ## How was this patch tested?
   Tests added.
