----------------------------------------
Summary: hivemetastore-report.json.tmp permission errors in hive
metastore, HS2 logs
Key: AMBARI-19558
URL: https://issues.apache.org/jira/browse/AMBARI-19558
Project: Ambari
Issue Type: Bug
Components: ambari-server
Affects Versions: trunk, 2.5.0
Reporter: Dmytro Grinenko
Assignee: Dmytro Grinenko
Priority: Critical
Fix For: trunk, 2.5.0
Noticed that the test cluster has lots of "hivemetastore-report.json.tmp
(Permission denied)" errors (every 5 seconds).
It is happening because user hive is running as user custom-hive while only
user hive has permission for /var/log/hive/ . This location is determined by
the config hive.service.metrics.file.location, which is set to
/var/log/hive/hivemetastore-report.json . The log4j logs are going into
/grid/0/log/hive/.
A fix would be to change value of this config to use whatever logging directory
is being used instad of hardcoding to /var/log/hive/. However, we are already
publishing the metrics via graphana, so this is not needed.
A quick fix would be to change the config to
hive.service.metrics.reporter=HADOOP2 in hive-server2-site and hive-metastore .
The old value is -
hive.service.metrics.reporter=JSON_FILE, JMX, HADOOP2. The suggested change
above will remove JMX as well, as we anyway aren't setting any of the required
JMX params. Setting JMX reporter is an unnecessary overhead.
