Jesus Camacho Rodriguez created HIVE-15583: ----------------------------------------------
Summary: CTAS query removes leading underscore from column names with CBO Key: HIVE-15583 URL: https://issues.apache.org/jira/browse/HIVE-15583 Project: Hive Issue Type: Bug Components: CBO Affects Versions: 2.2.0 Reporter: Jesus Camacho Rodriguez Assignee: Jesus Camacho Rodriguez Priority: Minor L209 in PlanModifierForASTConv.java: {code:java} if (colAlias.startsWith("_")) { colAlias = colAlias.substring(1); colAlias = getNewColAlias(newSelAliases, colAlias); } {code} I would like to explore if we can just remove this limitation. For instance, due to this issue, when we create a table with Druid storage handler, we need to add an additional underscore for column names as Druid is expecting columns with a certain name. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
