Examples with TableSchema org.apache.hadoop.hbase.shaded.protobuf.generated.HBaseProtos.TableSchema used on opensource projects

Example 1 with TableSchema

use of org.apache.hadoop.hbase.shaded.protobuf.generated.HBaseProtos.TableSchema 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 TableSchema

use of org.apache.hadoop.hbase.shaded.protobuf.generated.HBaseProtos.TableSchema in project hbase by apache.

the class ProtobufUtil method convertToTableSchema.

/**
   * Converts an HTableDescriptor to TableSchema
   * @param htd the HTableDescriptor
   * @return Convert the current {@link HTableDescriptor} into a pb TableSchema instance.
   */
public static TableSchema convertToTableSchema(HTableDescriptor htd) {
    TableSchema.Builder builder = TableSchema.newBuilder();
    builder.setTableName(toProtoTableName(htd.getTableName()));
    for (Map.Entry<Bytes, Bytes> e : htd.getValues().entrySet()) {
        BytesBytesPair.Builder aBuilder = BytesBytesPair.newBuilder();
        aBuilder.setFirst(UnsafeByteOperations.unsafeWrap(e.getKey().get()));
        aBuilder.setSecond(UnsafeByteOperations.unsafeWrap(e.getValue().get()));
        builder.addAttributes(aBuilder.build());
    }
    for (HColumnDescriptor hcd : htd.getColumnFamilies()) {
        builder.addColumnFamilies(convertToColumnFamilySchema(hcd));
    }
    for (Map.Entry<String, String> e : htd.getConfiguration().entrySet()) {
        NameStringPair.Builder aBuilder = NameStringPair.newBuilder();
        aBuilder.setName(e.getKey());
        aBuilder.setValue(e.getValue());
        builder.addConfiguration(aBuilder.build());
    }
    return builder.build();
}

Example 3 with TableSchema

use of org.apache.hadoop.hbase.shaded.protobuf.generated.HBaseProtos.TableSchema in project hbase by apache.

the class HTableDescriptor method parseFrom.

/**
   * @param bytes A pb serialized {@link HTableDescriptor} instance with pb magic prefix
   * @return An instance of {@link HTableDescriptor} made from <code>bytes</code>
   * @throws DeserializationException
   * @throws IOException
   * @see #toByteArray()
   */
public static HTableDescriptor parseFrom(final byte[] bytes) throws DeserializationException, IOException {
    if (!ProtobufUtil.isPBMagicPrefix(bytes)) {
        throw new DeserializationException("Expected PB encoded HTableDescriptor");
    }
    int pblen = ProtobufUtil.lengthOfPBMagic();
    TableSchema.Builder builder = TableSchema.newBuilder();
    TableSchema ts;
    try {
        ProtobufUtil.mergeFrom(builder, bytes, pblen, bytes.length - pblen);
        ts = builder.build();
    } catch (IOException e) {
        throw new DeserializationException(e);
    }
    return ProtobufUtil.convertToHTableDesc(ts);
