Subject [jira] [Commented] (YARN-5470) Differentiate exactly match with regex in yarn log CLI
Date Fri, 05 Aug 2016 20:32:20 GMT

    [ https://issues.apache.org/jira/browse/YARN-5470?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15410028#comment-15410028

Vinod Kumar Vavilapalli commented on YARN-5470:

Sorry for pitching in late - seems usual now a days.

+    pw.println(" -regex                          Work with -log_files to find matched");
+    pw.println("                                 files by using java regex.");

Instead of this, why don't we make separate the options {{log_files}} and {{log_files_pattern}}
so they are completely independent and the user can specify only one one of them ? {{-regex}}
as a standalone boolean option doesn't look right.

> Since YARN-5089, we support regular expression in YARN log CLI "-logFiles" option. However,
we should differentiate exactly match with regex match as user could put something like "system.out"
here which have different semantics.
