我已经安装了 cloudera cdh4 release 我正在尝试在上面运行 mapreduce 作业。我收到以下错误 -->

我能够运行 hadoop-mapreduce-examples-2.0.0-cdh4.0.0.jar 中给出的示例程序。 但是当我的工作成功提交到 jobtracker 时，我收到了这个错误。看起来它正在尝试再次访问本地文件系统(虽然我已经在分布式缓存中设置了作业执行所需的所有库，但它仍然试图访问本地目录)。这个问题与用户权限有关吗？

我) Cloudera:~ # hadoop fs -ls hdfs://<MyClusterIP>:8020/显示 -

Found 8 items
drwxr-xr-x   - hbase hbase               0 2012-07-04 17:58 hdfs://<MyClusterIP>:8020/hbase<br/>

drwxr-xr-x   - hdfs  supergroup          0 2012-07-06 15:58 hdfs://<MyClusterIP>:8020/user<br/>

二) --- 以下没有结果 ----

hdfs@Cloudera:/etc/hadoop/conf> find . -name '**' | xargs grep "default.name"<br/>
hdfs@Cloudera:/etc/hbase/conf> find . -name '**' | xargs grep "default.name"<br/>

相反，我认为我们正在使用新的 APIS ->
fs.defaultFS --> hdfs://Cloudera:8020 我已经正确设置

尽管对于“fs.default.name”，我得到了 hadoop 集群 0.20.2(非 cloudera 集群)的条目

cass-hadoop@Pratapgad:~/hadoop/conf> find . -name '**' | xargs grep "default.name"<br/>
./core-default.xml:  <name>fs.default.name</name><br/>
./core-site.xml:  <name>fs.default.name</name><br/>

我认为 cdh4 默认配置应该在各自的目录中添加这个条目。 (如果它的错误)。

我用来运行程序的命令 -

hdfs@Cloudera:/home/cloudera/yogesh/lib> java -classpath hbase-tools.jar:hbase.jar:slf4j-log4j12-1.6.1.jar:slf4j-api-1.6.1.jar:protobuf-java-2.4.0a.jar:hadoop-common-2.0.0-cdh4.0.0.jar:hadoop-hdfs-2.0.0-cdh4.0.0.jar:hadoop-mapreduce-client-common-2.0.0-cdh4.0.0.jar:hadoop-mapreduce-client-core-2.0.0-cdh4.0.0.jar:log4j-1.2.16.jar:commons-logging-1.0.4.jar:commons-lang-2.5.jar:commons-lang3-3.1.jar:commons-cli-1.2.jar:commons-configuration-1.6.jar:guava-11.0.2.jar:google-collect-1.0-rc2.jar:google-collect-1.0-rc1.jar:hadoop-auth-2.0.0-cdh4.0.0.jar:hadoop-auth.jar:jackson.jar:avro-1.5.4.jar:hadoop-yarn-common-2.0.0-cdh4.0.0.jar:hadoop-yarn-api-2.0.0-cdh4.0.0.jar:hadoop-yarn-server-common-2.0.0-cdh4.0.0.jar:commons-httpclient-3.0.1.jar:commons-io-1.4.jar:zookeeper-3.3.2.jar:jdom.jar:joda-time-1.5.2.jar com.hbase.xyz.MyClassName

最佳答案

Even I phased the same problem in 2.0.0-cdh4.1.3 while running MR jobs. After adding the property in mapred.site.xml

<property>
<name>mapreduce.framework.name</name>
<value>yarn</value>
</property>

For running Hive job

export HIVE_USER=yarn

关于configuration - cdh4 hadoop-hbase PriviledgedActionException 为 :hdfs (auth:SIMPLE) cause:java. io.FileNotFoundException，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/11363692/
