Subject [jira] Commented: (HADOOP-5360) Move from cronjob based watchdog for Chukwa Agent and System metrics to daemon tools startup script
Date Thu, 05 Mar 2009 01:23:56 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-5360?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12679028#action_12679028
] 

Eric Yang commented on HADOOP-5360:
-----------------------------------

I like to avoid grouping of log file with CHUKWA_DATA.  The user should be able to configure
where the log file to be stored independent from CHUKWA_DATA.  We should not enforce var/log
(unix directory structure format) to CHUKWA_DATA neither.  I suggest to rename CHUKWA_PID_DIR
to CHUKWA_DATA_DIR, if we want to store cache data.

> Instead of waiting one minute for cron job based watchdog to check the pid file and determine
if the process is running.  Netops request this to be changed to use deamon tools to improve
the uptime of chukwa agent and system metrics.
