Andrew Wang updated HADOOP-13699: --------------------------------- Release Note: This changes the config var cycle detection introduced in 3.0.0-alpha1 by HADOOP-6871 such that it detects single-variable but not multi-variable loops. This also fixes resolution of multiple specifications of the same variable in a config value. > Configuration does not substitute multiple references to the same var > --------------------------------------------------------------------- > > Key: HADOOP-13699 > URL: https://issues.apache.org/jira/browse/HADOOP-13699 > Project: Hadoop Common > Issue Type: Bug > Components: conf > Affects Versions: 3.0.0-alpha1 > Reporter: Andrew Wang > Assignee: Andrew Wang > Priority: Critical > Attachments: HADOOP-13699.001.patch > > > Config var loop detection was originally introduced by HADOOP-6871. Due to > cycle detection changes in the trunk patch for HADOOP-11506, resolution for > multiple references to the same variable no longer resolved, e.g. > {noformat} > somekey = "${otherkey} ${otherkey}" > {noformat} > This loop detection business is fragile, expensive, and not in branch-2, so > let's reduce it. -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: common-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: common-issues-h...@hadoop.apache.org
