[jira] [Commented] (MESOS-294) Slaves should report last lines of stdout/stderr when an executor crashes

    [ https://issues.apache.org/jira/browse/MESOS-294?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13481616#comment-13481616 ] 

Benjamin Mahler commented on MESOS-294:
---------------------------------------

The new webui may help with this issue, as we've added the ability to browse files for executor runs.

> A lot of the questions I see for running Spark on Mesos need to be answered by "log into that slave and look at stderr/stdout", followed by an explanation on where to find that. It would be cool to have a feature where the last 20-30 lines of the file are sent back automatically to the master so it can print them. Often the problem is 'java not found' or something similar.
