Examples with GetTableDescriptorsRequest org.apache.hadoop.hbase.shaded.protobuf.generated.MasterProtos.GetTableDescriptorsRequest used on opensource projects

Example 1 with GetTableDescriptorsRequest

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

the class AsyncHBaseAdmin method getTableDescriptor.

@Override
public CompletableFuture<HTableDescriptor> getTableDescriptor(TableName tableName) {
    CompletableFuture<HTableDescriptor> future = new CompletableFuture<>();
    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) {
            future.completeExceptionally(error);
            return;
        }
        if (!tableSchemas.isEmpty()) {
            future.complete(ProtobufUtil.convertToHTableDesc(tableSchemas.get(0)));
        } else {
            future.completeExceptionally(new TableNotFoundException(tableName.getNameAsString()));
        }
    });
    return future;
}

Example 2 with GetTableDescriptorsRequest

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

the class TestMasterObserver method testTableDescriptorsEnumeration.

@Test(timeout = 180000)
public void testTableDescriptorsEnumeration() throws Exception {
    MiniHBaseCluster cluster = UTIL.getHBaseCluster();
    HMaster master = cluster.getMaster();
    MasterCoprocessorHost host = master.getMasterCoprocessorHost();
    CPMasterObserver cp = (CPMasterObserver) host.findCoprocessor(CPMasterObserver.class.getName());
    cp.resetStates();
    GetTableDescriptorsRequest req = RequestConverter.buildGetTableDescriptorsRequest((List<TableName>) null);
    master.getMasterRpcServices().getTableDescriptors(null, req);
    assertTrue("Coprocessor should be called on table descriptors request", cp.wasGetTableDescriptorsCalled());
