嗨，我正在尝试在raspberry pi3上安装hadoop，我可以运行除name node以外的所有程序，我搜索了所有可能的源代码，但在其他地方找不到任何这样的问题，我的pi运行的java版本是jdk.1.7
以下是我的配置参数：
hadoop-env.sh文件

# The maximum amount of heap to use, in MB. Default is 1000.
# export HADOOP_HEAPSIZE=
# export HADOOP_NAMENODE_INIT_HEAPSIZE=""
# Extra Java runtime options.  Empty by default.
# export HADOOP_OPTS="$HADOOP_OPTS -Djava.net.preferIPv4Stack=true"
# export HADOOP_OPTS="$HADOOP_OPTS -XX:-PrintWarnings -Djava.net.preferIPv4Stack=true"
export HADOOP_OPTS="$HADOOP_OPTS -Djava.library.path=$HADOOP_HOME/lib/native"
# Command specific options appended to HADOOP_OPTS when specified
export HADOOP_NAMENODE_OPTS="-Dhadoop.security.logger=${HADOOP_SECURITY_LOGGER:-INFO,RFAS} -Dhdfs.audit.logger=${HDFS_AUDIT_LOGGER:-INFO,NullAppender} $HADOOP_NAMENODE_OPTS"
export HADOOP_DATANODE_OPTS="-Dhadoop.security.logger=ERROR,RFAS $HADOOP_DATANODE_OPTS"
export HADOOP_SECONDARYNAMENODE_OPTS="-Dhadoop.security.logger=${HADOOP_SECURITY_LOGGER:-INFO,RFAS} -Dhdfs.audit.logger=${HDFS_AUDIT_LOGGER:-INFO,NullAppender} $HADOOP_SECONDARYNAMENODE_OPTS"
export HADOOP_NFS3_OPTS="$HADOOP_NFS3_OPTS"
export HADOOP_PORTMAP_OPTS="-Xmx512m $HADOOP_PORTMAP_OPTS"
# The following applies to multiple commands (fs, dfs, fsck, distcp etc)
export HADOOP_CLIENT_OPTS="-Xmx512m $HADOOP_CLIENT_OPTS"
# HADOOP_JAVA_PLATFORM_OPTS="-XX:-UsePerfData $HADOOP_JAVA_PLATFORM_OPTS"
# On secure datanodes, user to run the datanode as after dropping privileges.
# This**MUST**be uncommented to enable secure HDFS if using privileged ports
# to provide authentication of data transfer protocol.  This**MUST NOT**be
# defined if SASL is configured for authentication of data transfer protocol
# using non-privileged ports.
export HADOOP_SECURE_DN_USER=${HADOOP_SECURE_DN_USER}
# Where log files are stored.  $HADOOP_HOME/logs by default.
# export HADOOP_LOG_DIR=${HADOOP_LOG_DIR}/$USER
# Where log files are stored in the secure data environment.
export HADOOP_SECURE_DN_LOG_DIR=${HADOOP_LOG_DIR}/${HADOOP_HDFS_USER}
### 
# HDFS Mover specific parameters
### 
    # Specify the JVM options to be used when starting the HDFS Mover.
# These options will be appended to the options specified as HADOOP_OPTS
# and therefore may override any similar flags set in HADOOP_OPTS
# 
# export HADOOP_MOVER_OPTS=""
### 
# Advanced Users Only!
### 
# The directory where pid files are stored. /tmp by default.
# NOTE: this should be set to a directory that can only be written to by
# the user that will run the hadoop daemons.  Otherwise there is the
# potential for a symlink attack.
export HADOOP_PID_DIR=${HADOOP_PID_DIR}
export HADOOP_SECURE_DN_PID_DIR=${HADOOP_PID_DIR}
# A string representing this instance of hadoop. $USER by default.
export HADOOP_IDENT_STRING=$USER
export JAVA_HOME=$(readlink -f /usr/bin/java | sed "s:bin/java::")
export HADOOP_HEAPSIZE=250

core-site.xml文件

<configuration>
   <property>
      <name>fs.default.name</name>
      <value>hdfs://localhost:9000</value>
   </property>
</configuration>

hdfs-site.xml文件

<configuration>
      <property>
        <name>dfs.replication</name>
            <value>1</value>
      </property>
      <property>
            <name>dfs.namenode.name.dir</name>
            <value>file:/opt/hadoop/hadoop_data/hdfs/namenode</value>
      </property>
      <property>
            <name>dfs.datanode.name.dir</name>
            <value>file:/opt/hadoop/hadoop_data/hdfs/datanode</value>
      </property>
    </configuration>

在运行./start-dfs.sh和./start.yarn.sh之后，当我键入jps时，以下节点deamons可见

13018 SecondaryNameNode
   12735 DataNode
   13265 ResourceManager
   13382 NodeManager
   17525 Jps

想知道我做错了什么吗
