Example 1 with TAppend

use of org.apache.hadoop.hbase.thrift.generated.TAppend in project hbase by apache.

the class TestThriftServer method doTestAppend.

/**
 * Appends the value to a cell and checks that the cell value is updated properly.
 */
public static void doTestAppend() throws Exception {
    ThriftHBaseServiceHandler handler = new ThriftHBaseServiceHandler(UTIL.getConfiguration(), UserProvider.instantiate(UTIL.getConfiguration()));
    handler.createTable(tableAname, getColumnDescriptors());
    try {
        List<Mutation> mutations = new ArrayList<>(1);
        mutations.add(new Mutation(false, columnAname, valueAname, true));

    } finally {
        handler.disableTable(tableAname);
        handler.deleteTable(tableAname);
    }
}

Example 2 with TAppend

use of org.apache.hadoop.hbase.thrift.generated.TAppend in project hbase by apache.

the class ThriftHBaseServiceHandler method append.

@Override
public List<TCell> append(TAppend tappend) throws IOError, TException {
    if (tappend.getRow().length == 0 || tappend.getTable().length == 0) {
        throw new TException("Must supply a table and a row key; can't append");
    }
    Table table = null;
    try {
        table = getTable(tappend.getTable());
        Append append = ThriftUtilities.appendFromThrift(tappend);
        Result result = table.append(append);
        return ThriftUtilities.cellFromHBase(result.rawCells());
    } catch (IOException e) {
        LOG.warn(e.getMessage(), e);
        throw getIOError(e);
    } finally {
        closeTable(table);
    }
}

Example 3 with TAppend

use of org.apache.hadoop.hbase.thrift.generated.TAppend in project hbase by apache.

the class ThriftUtilities method appendFromThrift.

/**
 * From a {@link TAppend} create an {@link Append}.
 * @param tappend the Thrift version of an append.
 * @return an increment that the {@link TAppend} represented.
 */
public static Append appendFromThrift(TAppend tappend) {
    Append append = new Append(tappend.getRow());
    List<ByteBuffer> columns = tappend.getColumns();
    List<ByteBuffer> values = tappend.getValues();
    if (columns.size() != values.size()) {
        throw new IllegalArgumentException("Sizes of columns and values in tappend object are not matching");
    }
    int length = columns.size();
    for (int i = 0; i < length; i++) {
        byte[][] famAndQf = CellUtil.parseColumn(getBytes(columns.get(i)));
        append.addColumn(famAndQf[0], famAndQf[1], getBytes(values.get(i)));
