我在datanodes的日志中看到了这一点.这可能是因为我将500万个文件复制到hdfs:
java.lang.IllegalStateException: com.google.protobuf.InvalidProtocolBufferException: Protocol message was too large. May be malicious.

我只是使用hadoop fs -put ….将文件复制到hdfs.最近我开始在客户端获取这些类型的消息:
15/06/30 15:00:58 INFO hdfs.DFSClient:无法完成/pdf-nxml/file1.nxml.COPYING重试…
15/06/30 15:01:05 INFO hdfs.DFSClient:无法完成/pdf-nxml/2014-full/file2.nxml.COPYING重试…
我得到一个如上所述的msg每分钟说3次.但是例外在数据节点上更频繁.
我怎样才能解决这个问题?

我不得不重新启动hadoop,现在它无法在每个datanode的日志文件中正确启动:
