Examples with WALFactory org.apache.hadoop.hbase.wal.WALFactory used on opensource projects

Example 1 with WALFactory

use of org.apache.hadoop.hbase.wal.WALFactory in project hbase by apache.

the class HBaseTestingUtility method createWal.

/**
   * Create an unmanaged WAL. Be sure to close it when you're through.
   */
public static WAL createWal(final Configuration conf, final Path rootDir, final HRegionInfo hri) throws IOException {
    // The WAL subsystem will use the default rootDir rather than the passed in rootDir
    // unless I pass along via the conf.
    Configuration confForWAL = new Configuration(conf);
    confForWAL.set(HConstants.HBASE_DIR, rootDir.toString());
    return (new WALFactory(confForWAL, Collections.<WALActionsListener>singletonList(new MetricsWAL()), "hregion-" + RandomStringUtils.randomNumeric(8))).getWAL(hri.getEncodedNameAsBytes(), hri.getTable().getNamespace());
