Hadoop命令不能从java prcoessbuilder执行

Question

我有这个脚本。

log_file_name=dataProcessor
export pwd=`pwd`
echo "in data processing"
log_file_path=LOGS/data-processor/
logfile=$log_file_path$log_file_name.log
log_file_home_path=LOGS
export LOG_FILE_HOME_PATH=$log_file_home_path
export DATA_EXTRACTION_CONFIG_FILE_LOCATION=$pwd/config.properties
export LIBJARS=/home/data-extraction/2.12.2.1/data-extraction/lib/*.jar
export HADOOP_CLASSPATH=$HADOOP_CLASSPATH:/home/abc/lib/*.jar
echo `$HADOOP_CLASSPATH`
hadoop jar data-processor-*.jar com.impl.JobSubmission -libjars ${LIBJARS} &> $log_file_home_path/process.log
echo "in data processing done"

当我从putty执行它时，它工作正常，但当我们使用java ProcessBuilder执行它时，它失败了。它会失败，并显示“未找到Hadoop命令”错误。下面是我用来执行脚本的Java代码。

ProcessBuilder builder = new ProcessBuilder(command.trim());
//builder.redirectErrorStream(true);
Process process = builder.start();
exitStatus = process.waitFor();
BufferedReader reader =
            new BufferedReader(new InputStreamReader(process.getInputStream()));

String line = "";
while ((line = reader.readLine()) != null) {
  output.append(line + "\n");
  System.out.print(line);
}

问题是另一个脚本。脚本一(1)启动Java应用程序，该应用程序在内部调用第二个脚本(S2)，该脚本正在下降。脚本一(S1)设置了无效的路径，而不是PATH，使用了PATH，这造成了整个问题。
