Я настроил gridgain-hadoop-os-6.6.2.zip и выполнил следующие шаги, как указано в docs/hadoop_readme.pdf
. начал gridgain с помощью команды bin/ggstart.sh, теперь я запускаю простой код wordcount в gridgain с hadoop-2.2.0. с помощью командыОшибка GridGain: java.lang.NoClassDefFoundError: org/apache/hadoop/mapreduce/JobContext
hadoop jar $HADOOP_HOME/share/hadoop/mapreduce/*-mapreduce-examples-*.jar wordcount /input /output
шаги я попробовал:
Шаг 1: Извлеченные Hadoop-2.2.0 и gridgain-hadoop-os-6.6.2.zip файл в USR/локальную папку и изменилось имя папки gridgain как «gridgain».
Шаг 2: указан путь для экспорта GRIDGAIN_HOME =/USR/местные/gridgain .. и путь для Hadoop-2.2.0 с JAVA_HOME как
# Set Hadoop-related environment variables
export HADOOP_PREFIX=/usr/local/hadoop-2.2.0
export HADOOP_HOME=/usr/local/hadoop-2.2.0
export HADOOP_MAPRED_HOME=/usr/local/hadoop-2.2.0
export HADOOP_COMMON_HOME=/usr/local/hadoop-2.2.0
export HADOOP_HDFS_HOME=/usr/local/hadoop-2.2.0
export YARN_HOME=/usr/local/hadoop-2.2.0
export HADOOP_CONF_DIR=/usr/local/hadoop-2.2.0/etc/hadoop
export GRIDGAIN_HADOOP_CLASSPATH='/usr/local/hadoop-2.2.0/lib/*:/usr/local/hadoop-2.2.0/lib/*:/usr/local/hadoop-2.2.0/lib/*'
Шаг 3:
сейчас я запускаю команду как bin/setup-hadoop.sh
... ответ Y на каждое приглашение.
Шаг 4:
начал gridgain используя команду
бен/ggstart.sh
Шаг 5:
Теперь я создал каталог и закачанный файл с помощью:
hadoop fs -mkdir /input
hadoop fs -copyFromLocal $HADOOP_HOME/README.txt /input/WORD_COUNT_ME.
txt
Шаг 6:
Выполнение этой команды дает мне ошибку:
hadoop jar $HADOOP_HOME/share/hadoop/mapreduce/*-mapreduce-examples-*.
jar wordcount /input /output
Получение следующие ошибки:
