I have created a parcel and custom service descriptor (CSD) for Apache Drill but the service status will only report “Unknown Health” (question mark icon) when the Drill service is run from Cloudera Manager v5.4.3. No graphs will display on the Charts portion of the UI. Both “Informational Events” or “Important Events and Alerts” say “NO DATA”.   What I’ve done:   I modified the Apache Drill start script to make it compatible with supervisord as indicated by https://github.com/cloudera/cm_ext/wiki/Control-Scripts.  The service is now able to be started and stopped in a compatible way and the stdout.log and stderr.log in /var/run/cloudera-scm-agent/process/<NNNN>-drill-DRILLBIT_SERVER/logs/ support this.   Basic sanity testing has confirmed that Drill is working.   When the service is run, the status of the service will only show as "Unknown Health" in the Cloudera Manager Web UI.  Other roles (HDFS Datanode) running on the same cluster node are correctly reporting their status. Since supervisord is used to run, and I’m assuming monitor, the services it starts I used /usr/lib64/cmf/agent/build/env/bin/supervisorctl to see what it was reporting. According to it, drill is happily running which it is.   e.g. $ cd /var/run/cloudera-scm-agent/supervisor $ /usr/lib64/cmf/agent/build/env/bin/supervisorctl 5380-hdfs-DATANODE        RUNNING     pid 23842, updtime 6 days, 2:59:06 5393-drill-DRILLBIT_SERVER       RUNNING pid 28750, uptime 1 day, 23:38:34 cmflistener      RUNNING     pid 26151, uptime 9 days, 3:01:01   $ ps –ef | grep drill root      19265  16618  0          19:29   pts/1    00:00:00          grep drill drill      28750  26150  0          Jan25   ?          00:03:31          /usr/java/default/jre/bin/java –Dlog.path=/opt/cloudera/parcels/APACHE_DRILL-1.4.0/log/drillbit.log …   So, is there something else which is reporting the status of the service to the Cloudera Manager Web UI? Any suggestions on what I should be looking at to fix this problem?    I appreciate any advice you can offer.   Thanks. ... View more
