The log file path of the MRS cluster is /var/log/Bigdata. The following table lists the log types.

Table 1 Log types

Log Type

Description

Installation logs

Installation logs record information about FusionInsight Manager, cluster, and service installation to help users locate installation errors.

Run logs

Run logs record the running track information, debugging information, status changes, potential problems, and error information generated during the running of services.

Audit logs

Audit logs record information about users' activities and operation instructions, which can be used to locate fault causes in security events and determine who are responsible for these faults.

After the multi-instance function is enabled, if the system administrator adds multiple HBase, Hive, and Spark service instances, the log description, log level, and log format of the newly added service instances are the same as those of the original service logs. Service instance logs are stored separately in the /var/log/Bigdata/servicenameN directory. The audit logs of the HBase and Hive service instances are stored in the /var/log/Bigdata/audit/servicenameN directory. For example, the logs of HBase1 are stored in the /var/log/Bigdata/hbase1 and /var/log/Bigdata/audit/hbase1 directories.

FusionInsight Manager audit logs are stored in the database. You can view and export the audit logs on the Audit page.

The following table lists the directories to store component audit logs. Audit log files of some components are stored in /var/log/Bigdata/audit, such as HDFS, HBase, MapReduce, Hive, Hue, YARN, Storm, and ZooKeeper. The component audit logs are automatically compressed and backed up to /var/log/Bigdata/audit/bk at 03: 00 every day. A maximum of latest 90 compressed backup files are retained, and the backup time cannot be changed. Configure the number of reserved audit log files. For details, see Configuring the Number of Local Backup Audit Log Files.

Audit log files of other components are stored in the component log directory.
