Subject [jira] [Commented] (HADOOP-15200) Missing DistCpOptions constructor breaks downstream DistCp projects in 3.0
Date Tue, 20 Feb 2018 20:06:01 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-15200?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16370547#comment-16370547

Mingliang Liu commented on HADOOP-15200:
----------------------------------------

HADOOP-14267 was marked as incompatible change when it was proposed. The goal and the reason
behind that was very clear in the description. Clients moving to 3.0 were expected to use
the new Builder pattern for constructing DistCpOptions. You can add workaround to bring back
any constructor for general use case, but reverting the origin change does not make sense
to me. Thanks,

> Post HADOOP-14267, the constructor for DistCpOptions was removed and will break any project
using it for java based implementation/usage of DistCp. This JIRA would track next steps required
to reconcile/fix this incompatibility.
