Impact on the System If the average RPC queuing time of the Guardian TokenServer instance exceeds the threshold, service access to OBS may slow down or even OBS cannot be accessed. Possible Causes The alarm threshold is improperly configured.
As a result, OBS cannot be accessed. Possible Causes An underlying interface of ECS is abnormal. Handling Procedure Collect fault information. On FusionInsight Manager, choose O&M. In the navigation pane on the left, choose Log > Download.
Log in to the OBS management console, click Parallel File System, click the name of the OBS parallel file system where the Hive table resides, and view the value of Endpoint on the overview page.
OBS Path: Select the name of the created OBS parallel file system, find the book_score.txt file, select I confirm that the selected script is secure, and I understand the potential risks and accept the possible exceptions or impacts on the cluster, and click OK.

When importing data from a relational database to HDFS or OBS, you do not need to configure data conversion. Data is separated by commas (,) and saved to HDFS or OBS. When exporting data from HDFS or OBS to a relational database, you do not need to configure data conversion.

Cause Analysis When the load command is used to import data to the Hive table across file systems (for example, the original data is stored in the HDFS but the Hive table data is stored in the OBS), and the file length is greater than the threshold (32 MB by default).

If a message displays indicating that OBS server cannot be connected, repeat 3. Click Save. If a Loader job has integrated into a Loader link, editing the link parameters may affect Loader running. Deleting a Link On the Loader page, click Manage links.
Impact on the System Some hot data on the local disk is moved to OBS, affecting the read and write performance of the system. Possible Causes The local disk capacity configured for cold-hot separation on the ClickHouseServer node is too small.
