场景：
NameNode节点：master
DataNode节点：slave1 ， slave2
1，往hdfs中put文件的时候报以下错误，但是执行结果是正常的，：
[hdfs@master ~]$ hadoop fs -put /file1.tgz /tmp 17/07/25 00:43:29 INFO hdfs.DFSClient: Exception in createBlockOutputStream org.apache.hadoop.hdfs.security.token.block.InvalidBlockTokenException: Got access token error, status message , ack with firstBadLink as 10.1.3.35:50010 at org.apache.hadoop.hdfs.protocol.datatransfer.DataTransferProtoUtil.checkBlockOpStatus(DataTransferProtoUtil.java:134) at org.apache.hadoop.hdfs.DFSOutputStream$DataStreamer.createBlockOutputStream(DFSOutputStream.java:1393) at org.apache.hadoop.hdfs.DFSOutputStream$DataStreamer.nextBlockOutputStream(DFSOutputStream.java:1295) at org.apache.hadoop.hdfs.DFSOutputStream$DataStreamer.run(DFSOutputStream.java:463) 17/07/25 00:43:29 INFO hdfs.DFSClient: Abandoning BP-1644766071-10.1.3.39-1499963302012:blk_1073741943_1124

2，经过排查防火墙已经关闭，hdfs状态是正常的，运行服务检查也正常，最后发现原因是slave2节点和其他节点时间不一致，时钟校准之后put文件正常。
