JAVA执行Linux命令报错Cannot run program error=2 , No such file or directory
JAVA使用ProcessBuilder运行Linux命令报错： start failed:Cannot run program "xxx" (in directory "xx"): error=2, No such file or directory。
网上找了各种资料都没解决，最后想起azkaban的源码里也是用的ProcessBuilder来执行shell命令，于是翻了一下代码，找到了解决方案，把azkaban里的partitionCommandLine这个方法对command做一下处理，就ok了。
代码如下：
run_command(partitionCommandLine(command), work_path);
/**
*执行命令
*/
public boolean run_command(final String[] command, final File work_path) throws IOException, InterruptedException {
log.info("COMMAND:" + command);
List<String> result_list = new ArrayList<>();
ProcessBuilder hiveProcessBuilder = new ProcessBuilder(command);
hiveProcessBuilder.directory(work_path);
hiveProcessBuilder.redirectErrorStream(true);
Process hiveProcess = hiveProcessBuilder.start();
BufferedReader std_input = new BufferedReader(new InputStreamReader(hiveProcess.getInputStream(), "UTF-8"));
BufferedReader std_error = new BufferedReader(new InputStreamReader(hiveProcess.getErrorStream(), "UTF-8"));
String line;
while ((line = std_input.readLine()) != null) {
result_list.add(line);
}
while ((line = std_error.readLine()) != null) {
log.error(line);
}
hiveProcess.waitFor();
if (hiveProcess.exitValue() != 0) {
log.error("failed to execute:" + command);
return false;
}
log.info("execute success:" + command);
IOUtils.closeQuietly(std_input);
IOUtils.closeQuietly(std_error);
return true;
}
/**
*对命令进行处理
*/
public static String[] partitionCommandLine(final String command) {
final ArrayList<String> commands = new ArrayList<>();
int index = 0;
StringBuffer buffer = new StringBuffer(command.length());
boolean isApos = false;
boolean isQuote = false;
while (index < command.length()) {
final char c = command.charAt(index);
switch (c) {
case ' ':
if (!isQuote && !isApos) {
final String arg = buffer.toString();
buffer = new StringBuffer(command.length() - index);
if (arg.length() > 0) {
commands.add(arg);
}
} else {
buffer.append(c);
}
break;
case '\'':
if (!isQuote) {
isApos = !isApos;
} else {
buffer.append(c);
}
break;
case '"':
if (!isApos) {
isQuote = !isQuote;
} else {
buffer.append(c);
}
break;
default:
buffer.append(c);
}
index++;
}
if (buffer.length() > 0) {
final String arg = buffer.toString();
commands.add(arg);
}
return commands.toArray(new String[commands.size()]);
}
