windows出现的话需要额外的设置

hadoop util 放 HADOOP/bin, 增加环境变量

吧hadoop.dll 复制到system32

hadoop2.6 配置注意点

终于能用了,都快崩溃了
ERROR org.apache.hadoop.hdfs.server.namenode.SecondaryNameNode: Exception in doCheckpoint
和之前种种异常,
列下需要注意的地方:

1:9000和9001, 这俩设置成统一的
2:虚拟机iptables 要关掉,有可能把端口封掉
3:hostname 跟hosts里设置成一样的会比较方便,生成id_rsa.pub的时候里面的路径就自动跟计算机名一致了
4: 我是用虚拟机的,1个master 1个slave 在slaves里把 master,slave1都加上了。

额外的诡异问题,配置好后运行无异常。但用测试demo,wordcount无法生成输出内容。
什么都没动,没关机器,第二天又自己好了。。

ucenter ssl邮件发送

163邮箱已经不支持非ssl邮件发送了,但ucenter不支持ssl发送,需要微调下

sendmail.inc.php

40行左右

} elseif($mail_setting[‘mailsend’] == 2) {

/*
*自定义ssl发送邮件
*/
$mail = new MySendMail();
$mail->setServer($mail_setting['mailserver'], $mail_setting['mailauth_username'], $mail_setting['mailauth_password'], $mail_setting['mailport'], true); //到服务器的SSL连接
//如果不需要到服务器的SSL连接,这样设置服务器:$mail->setServer("smtp.126.com", "XXX@126.com", "XXX");
$mail->setFrom($mail_setting['mailfrom']);
$mail->setReceiver($mail['email_to']);
$mail->setMail($mail['subject'], "<b>tesaaat</b>");
return $mail->sendMail($mail[message]);

邮件发送类,可以贴在最底下,搜的,测试可用。

/**
 * 邮件发送类
 * 支持发送纯文本邮件和HTML格式的邮件,可以多收件人,多抄送,多秘密抄送,带附件(单个或多个附件),支持到服务器的ssl连接
 * 需要的php扩展:sockets、Fileinfo和openssl。
 * @example
 * $mail = new MySendMail();
 * $mail->setServer("XXXXX", "XXXXX@XXXXX", "XXXXX"); //设置smtp服务器
 * $mail->setServer("XXXXX", "XXXXX@XXXXX", "XXXXX", 465, true); //设置smtp服务器,到服务器的ssl连接
 * $mail->setFrom("XXXXX"); //设置发件人
 * $mail->setReceiver("XXXXX"); //设置收件人,多个收件人,调用多次
 * $mail->setCc("XXXX"); //设置抄送,多个抄送,调用多次
 * $mail->setBcc("XXXXX"); //设置秘密抄送,多个秘密抄送,调用多次
 * $mail->addAttachment("XXXX"); //添加附件,多个附件,调用多次
 * $mail->setMail("test", "test"); //设置邮件主题、内容
 * $mail->sendMail(); 发送

python运行cmd命令行设置超时

网上文章一般都是用的这个方法

p = Popen(cmd,shell=True,stdout=PIPE, stderr=PIPE)

然后 p.poll() 可以获得状态,如果不是None,就是完成了。

不知道是不是windows的问题,运行dir这样的没事,如果运行ffmpeg就不行了,一直是None,无法获得状态。

 

最后用了比较原始的办法,开个线程运行cmd命令,主线程验证是否完成和是否超时。

命令行线程:

class CommandThread(threading.Thread):
    def __init__(self,cmd):
        threading.Thread.__init__(self)

        self.cmd=cmd
        self.result='';
        self.over=0;
        pass

    def run(self):
        try:
            strresult=subprocess.getoutput(self.cmd)
            self.result=strresult
            self.over=1
            return

        except Exception as e:
            print("cmd err")
        self.over=1
        pass

主线程:

@staticmethod
def cmd(command, timeout=10):
    try:

        cmdThread=CommandThread(command);
        cmdThread.start();
        t_beginning = time.time()
        seconds_passed = 0
        while True:
            if(cmdThread.over==1):
                str=cmdThread.result;
                break;
            seconds_passed = time.time() - t_beginning
            if timeout and seconds_passed > timeout:
                print("time out le;")
                break;
            time.sleep(0.1)

        # LogUtil.log(str)
        return str

    except Exception as e:
        print(e)
    return None

就是这个样子,因为sleep可能会有0.1的延迟,但是能解决ffmpeg命令行莫名其妙卡死的问题。
