Examples with PBImageXmlWriter org.apache.hadoop.hdfs.tools.offlineImageViewer.PBImageXmlWriter used on opensource projects

Example 1 with PBImageXmlWriter

use of org.apache.hadoop.hdfs.tools.offlineImageViewer.PBImageXmlWriter in project hadoop by apache.

the class TestSnapshot method testOfflineImageViewer.

/**
   * Test if the OfflineImageViewerPB can correctly parse a fsimage containing
   * snapshots
   */
@Test
public void testOfflineImageViewer() throws Exception {
    runTestSnapshot(1);
    // retrieve the fsimage. Note that we already save namespace to fsimage at
    // the end of each iteration of runTestSnapshot.
    File originalFsimage = FSImageTestUtil.findLatestImageFile(FSImageTestUtil.getFSImage(cluster.getNameNode()).getStorage().getStorageDir(0));
    assertNotNull("Didn't generate or can't find fsimage", originalFsimage);
    PrintStream o = new PrintStream(NullOutputStream.NULL_OUTPUT_STREAM);
    PBImageXmlWriter v = new PBImageXmlWriter(new Configuration(), o);
    v.visit(new RandomAccessFile(originalFsimage, "r"));
}

Example 2 with PBImageXmlWriter

use of org.apache.hadoop.hdfs.tools.offlineImageViewer.PBImageXmlWriter in project hadoop by apache.
