Subject [jira] [Commented] (HIVE-10380) CBO (Calcite Return Path): Add QBId to TableScan digest
Date Fri, 17 Apr 2015 18:55:59 GMT

    [ https://issues.apache.org/jira/browse/HIVE-10380?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14500434#comment-14500434
] 

Jesus Camacho Rodriguez commented on HIVE-10380:
------------------------------------------------

[~jpullokkaran], QBID already contains the table alias. It is generated by the following method:

{noformat}
  protected String getAliasId(String alias, QB qb) {
    return (qb.getId() == null ? alias : qb.getId() + ":" + alias).toLowerCase();
  }
{noformat}
