Example 41 with XAttr

use of org.apache.hadoop.fs.XAttr in project hadoop by apache.

the class TestJsonUtil method testToXAttrMap.

@Test
public void testToXAttrMap() throws IOException {
    String jsonString = "{\"XAttrs\":[{\"name\":\"user.a1\",\"value\":\"0x313233\"}," + "{\"name\":\"user.a2\",\"value\":\"0x313131\"}]}";
    ObjectReader reader = new ObjectMapper().readerFor(Map.class);
    Map<?, ?> json = reader.readValue(jsonString);
    XAttr xAttr1 = (new XAttr.Builder()).setNameSpace(XAttr.NameSpace.USER).setName("a1").setValue(XAttrCodec.decodeValue("0x313233")).build();
    XAttr xAttr2 = (new XAttr.Builder()).setNameSpace(XAttr.NameSpace.USER).setName("a2").setValue(XAttrCodec.decodeValue("0x313131")).build();
    List<XAttr> xAttrs = Lists.newArrayList();
    xAttrs.add(xAttr1);
    xAttrs.add(xAttr2);
    Map<String, byte[]> xAttrMap = XAttrHelper.buildXAttrMap(xAttrs);
    Map<String, byte[]> parsedXAttrMap = JsonUtilClient.toXAttrs(json);
    Assert.assertEquals(xAttrMap.size(), parsedXAttrMap.size());
    Iterator<Entry<String, byte[]>> iter = xAttrMap.entrySet().iterator();
    while (iter.hasNext()) {
        Entry<String, byte[]> entry = iter.next();
        Assert.assertArrayEquals(entry.getValue(), parsedXAttrMap.get(entry.getKey()));
    }
}

Example 42 with XAttr

use of org.apache.hadoop.fs.XAttr in project SSM by Intel-bigdata.

the class DBAdapter method getXattrTable.

    QueryHelper queryHelper = new QueryHelper(sql);
    ResultSet rs;
    List<XAttr> list = new LinkedList<>();
    try {
        rs = queryHelper.executeQuery();
        while (rs.next()) {
            XAttr xAttr = new XAttr.Builder().setNameSpace(XAttr.NameSpace.valueOf(rs.getString("namespace"))).setName(rs.getString("name")).setValue(rs.getBytes("value")).build();
            list.add(xAttr);
        }
        return XAttrHelper.buildXAttrMap(list);
    } finally {
        queryHelper.close();
    }
}
