------------------------------------
Summary: Make the children of ExprNodeGenericFuncDesc immutable
Key: HIVE-29505
URL: https://issues.apache.org/jira/browse/HIVE-29505
Project: Hive
Issue Type: Task
Reporter: Thomas Rebele
Mutability makes the code more difficult to reason about, so in general it
should be avoided.
At least the list of children should not be modifiable from outside of
ExprNodeGenericFuncDesc.
Preferably even removing ExprNodeGenericFuncDesc#setChildren if possible.
