Mingliang Liu updated HDFS-10556: --------------------------------- Attachment: HDFS-10556-branch-2.001.patch > 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 > Attachments: HDFS-10556-branch-2.000.patch, > HDFS-10556-branch-2.001.patch > > > {{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
