【中文标题】由于输入字符串的 java.lang.NumberFormatException 导致 Apache Tez 作业失败：“30s”

【英文标题】：Apache Tez Job fails due to java.lang.NumberFormatException for input string: "30s"

【问题描述】：

我正在尝试在 tez 上对 Apache hive 执行查询，但不知何故我收到如下错误，我不知道如何解决它

Apache Hadoop 3.1.1 Apache Hive 3.1.0 Apache Tez 0.9.1

我的 tez-site.xml

【参考方案1】：

尝试在 hdfs-site.xml 中添加此属性

<property>
    <name>dfs.client.datanode-restart.timeout</name>
    <value>30</value>
</property>

【参考方案2】：

感谢您的回复..我已经检查了我的 hdfs-site.xml 没有设置表明将值指定为“30s”。

<property>
        <name>dfs.replication</name>
        <value>1</value>
</property>
<property>
    <name>dfs.namenode.name.dir</name>
    <value>file:///hadoopdata/hdfs/namenode</value>
</property>
<property>
    <name>dfs.datanode.data.dir</name>
    <value>file:///hadoopdata/hdfs/datanode</value>
</property>
<property>
    <name>dfs.blocksize</name>
    <value>268435456</value>
</property>
<property>
    <name>dfs.blocksize</name>
    <value>268435456</value>
</property>
<property>
    <name>dfs.namenode.handler.count</name>
    <value>100</value>
</property>
<property>
    <name>dfs.permissions.superusergroup</name>
    <value>hadoop</value>
    <description>The name of the group of super-users.</description>
</property>

【讨论】：

就我而言，“30s”没有设置，但正如@alen 建议的那样，添加属性然后它就可以工作了。 （相同版本的 Hadoop - 3.1.1）

问题在于默认值，显然是30s。

【参考方案3】：

属性dfs.client.datanode-restart.timeout 的默认值为30s。 This issue is related.

Here 提到了一种解决方法。它对我有用。
