Hadoop 2.7.2でPig-0.16.0 - エラー1002：エイリアスを保存できません

Question

私はPigバージョン0.16.0でUbuntu 14.04 LTSに疑似分散Hadoop 2.7.2をインストールしたPigラーニングを開始しました。以下のPIGとHadoopのための私の構成です -

ファイル：

#=============================================================== 
# Hadoop Variable List 

export JAVA_HOME=/usr/lib/jvm/java-9-oracle 
export HADOOP_INSTALL=/home/hadoop/hadoop 
export PATH=$PATH:$HADOOP_INSTALL/bin 
export PATH=$PATH:$HADOOP_INSTALL/sbin 
export HADOOP_MAPRED_HOME=$HADOOP_INSTALL 
export HADOOP_COMMON_HOME=$HADOOP_INSTALL 
export HADOOP_HDFS_HOME=$HADOOP_INSTALL 
export HADOOP_HOME=$HADOOP_INSTALL 
export YARN_HOME=$HADOOP_INSTALL 
export HADOOP_COMMON_LIB_NATIVE_DIR=$HADOOP_INSTALL/lib/native 
export HADOOP_OPTS="-Djava.library.path=$HADOOP_INSTALL/lib/native" 

#=============================================================== 
# PIG variable 
export PIG_HOME="/home/hadoop/pig" 
export PIG_INSTALL="$PIG_HOME" 
export PIG_CONF_DIR="$PIG_HOME/conf" 
export PIG_CLASSPATH="$HADOOP_INSTALL/conf" 
export HADOOPDIR="$HADOOP_INSTALL/conf" 
export PATH="$PIG_HOME/bin:$PATH" 

=======================

の.bashrc

と次は私があまりにも

hadoop@rajeev:~$ hadoop fs -ls -R /user/hadoop 
-rw-r--r-- 1 hadoop supergroup  540117 2016-07-15 12:48 /user/hadoop/myfile.txt 

HDFSにこのファイルをコピーし

-rw-rw-r-- 1 hadoop hadoop 540117 Jul 15 12:41 myfile.txt 
hadoop@rajeev:~$ pwd 
/home/hadoop 

ディレクトリそこから私が実行していブタであります

今、Gruntシェルで次のコマンドを実行すると、エラーが発生します。

grunt> a = load 'myfile.txt' as line; 
grunt> store a into 'c.out';

私はただのMapReduceモードでローカルモードでPIGを実行しないことにより、他の手段によってそれを解決しようとしたが、何も動作しているようだありません。これらの単純な2つのコマンドが失敗するたびに

を次のエラー・ログ・ファイルのプリントは、あなたの助けをリクエスト！

Answer 1

ロード先のフィールドの絶対パスとデータ型を指定します。

a = load 'hdfs://localhost:9001/user/hadoop/myfile.txt' AS (line:chararray); 
store a into 'hdfs://localhost:9001/user/hadoop/c.out';
