Subject [jira] [Commented] (SPARK-9636) Treat $SPARK_HOME as write-only
Date Wed, 05 Aug 2015 10:28:04 GMT

    [ https://issues.apache.org/jira/browse/SPARK-9636?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14655146#comment-14655146

Sean Owen commented on SPARK-9636:
----------------------------------

I'm not sure those are as obvious as defaults, or necessarily have write permission either.
Isn't the solution that {{SPARK_LOG_DIR}} should be set if needed?

> when starting spark scripts as user and it is installed in a directory the user has no
write permissions on, many things work fine, except for the logs (e.g. for {{start-master.sh}})
> logs are per default written to {{$SPARK_LOG_DIR}} or (if unset) to {{$SPARK_HOME/logs}}.
> if installed in this way, it should, instead of throwing an error, write logs to {{/var/log/spark/}}.
that’s easy to fix by simply testing a few log dirs in sequence for writability before trying
to use one. i suggest using {{$SPARK_LOG_DIR}} (if set) → {{/var/log/spark/}} → {{~/.cache/spark-logs/}}
→ {{$SPARK_HOME/logs/}}
