示例1: writeFlushRequestMarkerToWAL

import org.apache.hadoop.hbase.regionserver.wal.WALUtil; //导入方法依赖的package包/类
/**
 * Writes a marker to WAL indicating a flush is requested but cannot be complete due to various
 * reasons. Ignores exceptions from WAL. Returns whether the write succeeded.
 *
 * @param wal
 * @return whether WAL write was successful
 */
private boolean writeFlushRequestMarkerToWAL(WAL wal, boolean writeFlushWalMarker) {
  if (writeFlushWalMarker && wal != null && !writestate.readOnly) {
    FlushDescriptor desc = ProtobufUtil
        .toFlushDescriptor(FlushAction.CANNOT_FLUSH, getRegionInfo(), -1,
            new TreeMap<byte[], List<Path>>(Bytes.BYTES_COMPARATOR));
    try {
      WALUtil.writeFlushMarker(wal, this.htableDescriptor, getRegionInfo(), desc, true, mvcc);
      return true;
    } catch (IOException e) {
      LOG.warn(getRegionInfo().getEncodedName() + " : "
          + "Received exception while trying to write the flush request to wal", e);

  } catch (Throwable t) {
    LOG.warn("Received unexpected exception trying to write ABORT_FLUSH marker to WAL:" +
        StringUtils.stringifyException(t));
    // ignore this since we will be aborting the RS with DSE.
  }
  // we have called wal.startCacheFlush(), now we have to abort it
  wal.abortCacheFlush(this.getRegionInfo().getEncodedNameAsBytes());
