Lindorm:HBase API limits

Table naming

Table names can contain only letters, digits, and underscores (_). Periods, hyphens, and other special characters are not supported.

Cluster management operations

Lindorm does not support HBase API operations for cluster management, such as assign region and stopRegionServer. To monitor and manage your instance, use the Lindorm console and Lindorm Insight.

Coprocessors

Lindorm does not support HBase coprocessors. For more information, join a DingTalk group. For more information, see Technical support.

Underlying storage access

Lindorm grants limited permissions to access its underlying storage. To access the underlying storage, use the Hadoop Distributed File System (HDFS) protocol.

• Data import and export: See Introduction to LTS (formerly known as BDS).

• Data analytics with Apache Spark: See Use Spark to connect to and use LindormTable. Alternatively, call HBase API operations in Spark or use TableInputFormat in MapReduce.

• Bulk load operations: Call the HDFS API operations.

Custom filters

Lindorm does not support custom filters. To use a custom filter, package the filter class into a JAR file, then upload it to the lib directory on the server node or in HDFS. After uploading, either restart the server node or dynamically load the JAR file to validate the custom filter.

For questions about any of these limits, submit a ticket or join a DingTalk group. For more information, see Technical support.
