### 一：前面操作正确 ###

![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzQzNjg4NDcy_size_16_color_FFFFFF_t_70]

### 二：执行 ###

[hadoop@hadoop001 shell]$ yarn logs -applicationId application_1545664455577_0006

### 三：报错 ###

18/12/25 13:51:59 INFO client.RMProxy: Connecting to ResourceManager at /0.0.0.0:8032
    /tmp/logs/hadoop/logs/application_1545664455577_0006does not exist.
    Log aggregation has not completed or is not enabled.

### 四：解决：yarn-site.xml在这个文件下面添加 ###

<property>
            <name>yarn.log-aggregation-enable</name>
            <value>true</value>
     </property>
     <property>
            <name>yarn.nodemanager.log-aggregation.roll-monitoring-interval-seconds</name>
            <value>3600</value>
     </property>
     <property>
            <name>yarn.nodemanager.remote-app-log-dir</name>
            <value>/tmp/logs</value>
     </property>

sbin/stop-all.sh  
sbin/start-all.sh

### 还有一种可能： ###

[hadoop@hadoop001 hadoop]$ hdfs dfs -ls /tmp/logs
    ls: `/tmp/logs': No such file or directory
    [hadoop@hadoop001 hadoop]$ hdfs dfs -ls /tmp
    Found 1 items
    drwxr-xr-x   - hadoop supergroup          0 2018-12-25 17:47 /tmp/hadoop-yarn
    [hadoop@hadoop001 hadoop]$ hdfs dfs -mkdir /tmp/logs
    [hadoop@hadoop001 hadoop]$ hdfs dfs -ls /tmp
    Found 2 items
    drwxr-xr-x   - hadoop supergroup          0 2018-12-25 17:47 /tmp/hadoop-yarn
    drwxr-xr-x   - hadoop supergroup          0 2018-12-25 17:53 /tmp/logs
