Mingliang Liu created HDFS-10556: ------------------------------------ Summary: DistCpOptions should be validated automatically Key: HDFS-10556 URL: https://issues.apache.org/jira/browse/HDFS-10556 Project: Hadoop HDFS Issue Type: Bug Affects Versions: 2.8.0 Reporter: Mingliang Liu Assignee: Mingliang Liu
{{DistCpOptions}} can be set from command-line or may be set manually. In [HDFS-10397], we refactored the validation to make it simpler and more efficient. However, the newly added {{validate()}} method may not be automatically revoked. This is the major concern for existing downstreams that create the {{DistCpOptions}} manually instead of by parser, and have conflicting options. This jira is to make the validation happen automatically. A simple fix is to use the approach that validates in individual setters. This is a fix for {{branch-2}}. As a long-term fix, in [HDFS-10533], we're making the {{DistCpOptions}} immutable so that it will be hard, if not impossible, to use it wrongly by downstream applications. However, that code will only go to {{trunk}} branch as it breaks backwards-compatibility. -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: hdfs-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: hdfs-issues-h...@hadoop.apache.org
