我下面這個教程http://www.michael-noll.com/tutorials/running-hadoop-on-ubuntu-linux-single-node-cluster/Hadoop的:通過NameNode會在Ubuntu格式化HDFS文件系統12.04
注:是的,我知道我沒有安裝Hadoop的到/ usr /本地/ Hadoop的/ Hadoop的/但教程不
當我運行:
[email protected]:~$ /usr/local/hadoop/hadoop/bin/hadoop namenode -format
我得到
Warning: $HADOOP_HOME is deprecated.
/usr/local/hadoop/hadoop/bin/hadoop: line 320: /usr/lib/jvm/java-6-sun/bin/java: No such file or directory
/usr/local/hadoop/hadoop/bin/hadoop: line 390: /usr/lib/jvm/java-6-sun/bin/java: No such file or directory
代替的

代碼
用於在/ usr /本地/ Hadoop的/ Hadoop的/ bin中/ Hadoop的線320是:
JAVA_PLATFORM=`CLASSPATH=${CLASSPATH} ${JAVA} -Xmx32m ${HADOOP_JAVA_PLATFORM_OPTS}
org.apache.hadoop.util.PlatformName | sed -e "s/ /_/g"`
和線路390:
exec "$JAVA" -Dproc_$COMMAND $JAVA_HEAP_MAX $HADOOP_OPTS -classpath "$CLASSPATH" $CLASS "[email protected]"
任何想法如何我可以解決這個問題?
我只是編輯在/ usr /本地/ Hadoop的/ Hadoop的代碼/ bin/hadoop,以便查看正確的JDK。 – user1047260
