Subject [jira] [Resolved] (HADOOP-684) it would be nice to be able to view log and output files w/in the browser
Date Sat, 16 Jul 2011 17:08:00 GMT

     [ https://issues.apache.org/jira/browse/HADOOP-684?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

Harsh J resolved HADOOP-684.

    Resolution: Invalid

All log files are plain text files openable by a ton of tools out there, even browsers today,
and the DFS does carry a browser along in the web UI for the DFS files.

Logger levels can also be set and logs can be queried via the /logs and /logLevel areas of
any web UI under Hadoop.

Resolving as Invalid (now).

vs saving the file and opening an external application.
> one way to achieve this is to simply add ".txt" as a suffix to the relevant files, eg:

> it has been suggested that perhaps the content type of the log files could be specified,
thereby allowing for wider/richer support.
