Change subject: IMPALA-7867 (Part 1): Expose List in TreeNode, parser ...................................................................... Patch Set 3: (1 comment) http://gerrit.cloudera.org:8080/#/c/11954/2/fe/src/main/java/org/apache/impala/common/TreeNode.java File fe/src/main/java/org/apache/impala/common/TreeNode.java: http://gerrit.cloudera.org:8080/#/c/11954/2/fe/src/main/java/org/apache/impala/common/TreeNode.java@62 PS2, Line 62: ult = new A > You still can replace ArrayList with List instead of reverting everything. Good catch! Was a little too quick with my Eclipse diff tool... The way around the type issue is actually used later in this class: pass in the target class to allow runtime type checks. Either a) filter nodes that don't derive from the target class, or b) raise an error in this case. We'll leave this as an exercise for later. Won't be too hard: there are only a couple of uses of this function and the post-order version. -- To view, visit http://gerrit.cloudera.org:8080/11954 To unsubscribe, visit http://gerrit.cloudera.org:8080/settings Gerrit-Project: Impala-ASF Gerrit-Branch: master Gerrit-MessageType: comment Gerrit-Change-Id: Iebab7dccdb4b2fa0b5ca812beab0e8bdba39f539 Gerrit-Change-Number: 11954 Gerrit-PatchSet: 3 Gerrit-Owner: Paul Rogers <par0...@yahoo.com> Gerrit-Reviewer: Fredy Wijaya <fwij...@cloudera.com> Gerrit-Reviewer: Impala Public Jenkins <impala-public-jenk...@cloudera.com> Gerrit-Reviewer: Paul Rogers <par0...@yahoo.com> Gerrit-Comment-Date: Wed, 21 Nov 2018 03:28:56 +0000 Gerrit-HasComments: Yes
