Examples with FileFilter java.io.FileFilter used on opensource projects

Example 1 with FileFilter

use of java.io.FileFilter in project hadoop by apache.

the class JournalNode method getJournalsStatus.

// JournalNodeMXBean
@Override
public String getJournalsStatus() {
    // jid:{Formatted:True/False}
    Map<String, Map<String, String>> status = new HashMap<String, Map<String, String>>();
    synchronized (this) {
        for (Map.Entry<String, Journal> entry : journalsById.entrySet()) {
            Map<String, String> jMap = new HashMap<String, String>();
            jMap.put("Formatted", Boolean.toString(entry.getValue().isFormatted()));
            status.put(entry.getKey(), jMap);
        }
    }
    // It is possible that some journals have been formatted before, while the 
    // corresponding journals are not in journalsById yet (because of restarting
    // JN, e.g.). For simplicity, let's just assume a journal is formatted if
    // there is a directory for it. We can also call analyzeStorage method for
    // these directories if necessary.
    // Also note that we do not need to check localDir here since
    // validateAndCreateJournalDir has been called before we register the
    // MXBean.
    File[] journalDirs = localDir.listFiles(new FileFilter() {

        @Override
        public boolean accept(File file) {
            return file.isDirectory();
        }
    });
    for (File journalDir : journalDirs) {
        String jid = journalDir.getName();
        if (!status.containsKey(jid)) {
            Map<String, String> jMap = new HashMap<String, String>();
            jMap.put("Formatted", "true");
            status.put(jid, jMap);
        }
    }
    return JSON.toString(status);
}
