You can use the HBase API for Java to connect to Lindorm. Take note of the following limits:
- Lindorm table names can contain only letters, digits, and underscores (_).
- Lindorm does not support HBase API operations for managing clusters, such as assign region and stopRegionServer. If you want to manage clusters, log on to the Lindorm console and use the Lindorm Insight system.
- Lindorm does not support HBase coprocessors. If you want to obtain more information, join a DingTalk group. For more information, see Technical support.
- Limited permissions are granted to access the underlying storage of Lindorm. You can access the underlying storage of Lindorm over the HDFS protocol. For more information about how to import or export data, see Introduction to LTS (formerly known as BDS). For more information about how to use Spark to analyze data, see Use Spark to connect to and use LindormTable. You can also call the HBase API operations in Spark or call the TableInputFormat operation in MapReduce. If you want to perform bulk load operations, call the HDFS API operations.
- Lindorm does not support custom filters. If you want to specify a custom filter, encapsulate the code of the filter class into a JAR file and upload the file to the lib directory of the server node or HDFS. Then, restart the server node or dynamically load the JAR file to validate the custom filter.
If you have questions about the limits, submit a ticket or join a DingTalk group. For more information, see Technical support.
