hbase master log中一直报出如下错误，如何修复

hbase master log中一直报出如下错误，请问谁知道有谁遇过这个问题，如何修复呢
我们用的cloudera 5.4，对应的hbase版本是1.0.0

谷歌的protobuf有问题了吧。看看运行是否正常。
导致hbase快照的时候出问题了

如何查看protobuf有问题没，目前这个集群hadoop和hbase服务都是可以用的，在这个集群是通过hbase shell是可以做快照的并删除快照的，但是日志确一直持续报这个错，也不知道是哪个操作引起这个错误的

[mw_shl_code=bash,true]protoc --version[/mw_shl_code]

遇到了相同的问题，请问解决了吗？能否共享下解决方法，谢谢

原因分析:
查看了原代码，错误发生在从SnapshotFileCache 中getName()的时候抛出来的IOException，这个Cache默认是每5分钟刷新一次。当Cache中无法getName的时候，就会报告这个错误。所以，导致错误的原因，可能是Cache被清理了，已经不存在对应的SnapshotFileCache，清理Snapshot的进程拿不到对应的HTable （table_schema）

我们的解决方法：
整个Hbase Service重启，让系统重新初始化SnapshotFileCache。然后，Hbase Snapshot Clean就可以正常清理了。

原代码：
SnapshotHFileCleaner.java

[mw_shl_code=java,true]/** Refresh cache, by default, every 5 minutes */
  private static final long DEFAULT_HFILE_CACHE_REFRESH_PERIOD = 300000;

  /** File cache for HFiles in the completed and currently running snapshots */
  private SnapshotFileCache cache;

  @Override
  public synchronized boolean isFileDeletable(Path filePath) {
    try {
      return !cache.contains(filePath.getName());
    } catch (IOException e) {
      LOG.error("Exception while checking if:" + filePath + " was valid, keeping it just in case.",
        e);
      return false;
    }
  }
