Examples of org.kitesdk.data.hbase.manager.DefaultSchemaManager

org.kitesdk.data.hbase.manager.DefaultSchemaManager
The Default SchemaManager implementation. It uses a ManagedSchemaDao implementation, passed in the constructor, to read schema metadata, and persist schema metadata for schema creations and migrations.

  private HBaseMetadataProvider metadataProvider;
  private final URI repositoryUri;


  HBaseDatasetRepository(HBaseAdmin hBaseAdmin, HTablePool tablePool, URI repositoryUri) {
    this.tablePool = tablePool;
    this.schemaManager = new DefaultSchemaManager(tablePool);
    this.metadataProvider = new HBaseMetadataProvider(hBaseAdmin, schemaManager);
    this.repositoryUri = repositoryUri;
