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 00:19:56 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-5360?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12679011#action_12679011
] 

Jerome Boulon commented on HADOOP-5360:
---------------------------------------

Instead of having so many variables like LOG_DIR, PID_DIR and so on can you define CHUKWA_DATA
and get all the others variables defined relative to either CHUKWA_HOME, CHUKWA_CONF or CHUKWA_DATA.
That way Chukwa configuration will be much simpler.

CHUKWA_HOME contains all binaries
CHUKWA_CONF contains all config files
CHUKWA_DATA. contains all Chukwa's output

ex :
- log files ${CHUKWA_DATA}/var/log
- pid files ${CHUKWA_DATA}/var/run
- etc

if CHUKWA_DATA or  CHUKWA_CONF are undefined they should default back to CHUKWA_HOME/data
resp. CHUKWA_HOME/conf

> 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.
