19/03/26 21:28:08 INFO mapreduce.Job: map 0% reduce 0%19/03/26 21:28:12 INFO mapreduce.Job: Task Id : attempt_1552051424310_0114_m_000000_0, Status : FAILEDError: java.io.FileNotFoundException: Path is not a file: /g6/hadoop/20190326 at org.apache.hadoop.hdfs.server.namenode.INodeFile.valueOf(INodeFile.java:70) at org.apache.hadoop.hdfs.server.namenode.INodeFile.valueOf(INodeFile.java:56) at org.apache.hadoop.hdfs.server.namenode.FSNamesystem.getBlockLocationsUpdateTimes(FSNamesystem.java:1934) at org.apache.hadoop.hdfs.server.namenode.FSNamesystem.getBlockLocationsInt(FSNamesystem.java:1875) at org.apache.hadoop.hdfs.server.namenode.FSNamesystem.getBlockLocations(FSNamesystem.java:1855) at org.apache.hadoop.hdfs.server.namenode.FSNamesystem.getBlockLocations(FSNamesystem.java:1827) at org.apache.hadoop.hdfs.server.namenode.NameNodeRpcServer.getBlockLocations(NameNodeRpcServer.java:566) at org.apache.hadoop.hdfs.server.namenode.AuthorizationProviderProxyClientProtocol.getBlockLocations(AuthorizationProviderPro
执行的命令是
process_data=20190326
hadoop jar hadoop_train-1.0.jar com.g609.hadoop.etl.driver.LogETLDriver /g6/hadoop/$process_data/ /g6/hadoop/access/output/$process_data
经过分析最终发现因为在输入路径/g6/hadoop/$process_data/ 最后又加了一个/ 把这个斜线去掉在执行就可以了
