Component Introduction
Metadata is data about data. It is used to define data properties, specify data storage locations and historical data, retrieve resource data, and record information. In FusionInsight, metadata is used to describe the database table structures of HBase and Hive and relevant detailed information. Functions of metadata include synchronizing metadata manually or in a scheduled manner, editing label information, searching and retrieving metadata information, and uploading metadata to the FTP server.
Log Description
Log path: Metadata logs are stored in the following paths by default:
Run the installation logs: /var/log/Bigdata/metadata
Audit logs: /var/log/Bigdata/audit/metadata
Log archive rule: The automatic compression and archive function is enabled for Metadata run and audit logs. By default, when the size of a log exceeds 10 MB (the log file size threshold is configurable), the log is automatically compressed into a log file named in the following rule: <Original log file name>-<yyyy-mm-dd_hh-mm-ss>.[No.].<Original suffix>.zip.
