Example Codes

The following is a code snippet of file deletion. For complete codes, see the HdfsExample class in com.huawei.bigdata.hdfs.examples.

 
/**
 * delete the directory 
 *
 * @throws java.io.IOException
 */
private void rmdir() throws IOException {
    Path destPath = new Path(DEST_PATH);
    if (!deletePath(destPath)) {
        LOG.error("failed to delete destPath " + DEST_PATH);
        return;
    }
    LOG.info("success to delete path " + DEST_PATH);
}


/**
 * delete file path
 *
 * @param filePath
 * @return
 * @throws java.io.IOException
 */
private boolean deletePath(final Path filePath) throws IOException {
    if (!fSystem.exists(filePath)) {
        return false;
    }
    // fSystem.delete(filePath, true);
    return fSystem.delete(filePath, true);
}
