Summary: Vector initializer used for memory allocation in external sort is subject to aliasing Key: DRILL-6232 URL: https://issues.apache.org/jira/browse/DRILL-6232 Project: Apache Drill Issue Type: Bug Components: Execution - Flow Affects Versions: 1.13.0 Reporter: Padma Penumarthy Assignee: Padma Penumarthy Fix For: 1.14.0 vector initializer class builds hints for individual columns and saves them in a map with lookup key of column name. For children of map columns, this name will be parent name + "." + child column name. This can cause problem when we have dots in column names i.e. {{a.b(c) and a(b.c) will have the same key and can cause overwrites of each other values. Change this to use allocation routines in column size which do not have this problem. }} -- This message was sent by Atlassian JIRA (v7.6.3#76005)
