Example 1 with GetTableDescriptorsResponse

use of org.apache.hadoop.hbase.shaded.protobuf.generated.MasterProtos.GetTableDescriptorsResponse in project hbase by apache.

    this.<List<TableSchema>>newMasterCaller().action((controller, stub) -> this.<GetTableDescriptorsRequest, GetTableDescriptorsResponse, List<TableSchema>>call(controller, stub, RequestConverter.buildGetTableDescriptorsRequest(tableName), (s, c, req, done) -> s.getTableDescriptors(c, req, done), (resp) -> resp.getTableSchemaList())).call().whenComplete((tableSchemas, error) -> {
        if (error != null) {
