Subject [jira] [Updated] (YARN-3698) Make task attempt log files accessible from webapps
Date Thu, 04 Jun 2015 18:10:39 GMT

     [ https://issues.apache.org/jira/browse/YARN-3698?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Sreenath Somarajapuram updated YARN-3698:
-----------------------------------------
    Description: 
Currently we don't have direct access to an attempt's log file from web apps. The only available
option is through jobhistory, and that provides an HTML view of the log.

Requirements:
# A link to access the raw log file.
# A variant of the link with the following headers set, this enables direct download of the
file across all browsers.
    Content-Disposition: attachment; filename="attempt-id.log"
    Content-Type of text/plain
# Node manager redirects an attempt syslog view to the container view. Hence we are not able
to view the logs of a specific attempt.
Before redirection: http://sandbox.hortonworks.com:8042/node/containerlogs/container_1432048982252_0004_01_000002/root/syslog_attempt_1432048982252_0004_1_02_000000_0
After redirection: http://sandbox.hortonworks.com:19888/jobhistory/logs/sandbox.hortonworks.com:45454/container_1432048982252_0004_01_000002/container_1432048982252_0004_01_000002/root
