This jira will decide whether to make {{-q}} the default > for {{dfs -ls}} on a terminal. > This is a split of HADOOP-13079. The split gives us more time to debate the > proper default behavior and enables different target versions. > To test whether STDOUT is connected to a terminal, I will use > {{System.console() != null}}, fully aware its limitation. JNI {{isatty(3)}} > is possible but too problematic as pointed out by [~cmccabe]. > I will survey FsShell and hdfs commands and their proper expected default > behaviors. Thanks [~andrew.wang] for the suggestion. More jiras may follow. -- 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
