Cloudera CDH 5.7.2 / HBase：如何设置hfile.format.version？ [英] Cloudera CDH 5.7.2 / HBase: How to Set hfile.format.version?

问题描述

使用CDH 5.7.2-1.cdh5.7.2.po.18，我试图使用Cloudera Manager将HBase配置为使用可见性标签和授权，如下面的Cloudera社区帖子中所述：

使用Cloudera Manager，我已成功更新了Cloudera Manager Hbase可见性标签以下属性的值：

• hbase.coprocessor.region.classes：设置为org.apache.hadoop.hbase.security.visibility。 VisibilityController


• hbase.coprocessor.master.classes：设置为org.apache.hadoop.hbase.security.visibility.VisibilityController


• hbase.security。授权：设为true

不幸的是，无论出于何种原因，Cloudera Manager都不会将hfile.format.version变量le，所以我无法将它设置为3。

在更新上述三个变量后重新启动HBase时，角色日志中会显示以下错误：

错误org.apache.hadoop.hbase.coprocessor.CoprocessorHost：协处理器org.apache.hadoop.hbase.security.visibility.VisibilityController抛出java.lang.RuntimeException：要求保持安全标签的最小HFile版本为3。请考虑相应地设置hfile.format.version。

我很想相应地设置hfile.format.version，但是......我怎么做，当它不是暴露在Cloudera Manager中？例如，我可以修改文件系统上的某个配置文件吗？ Cloudera Manager必须从某个地方获取当前设置。

谢谢！

解决方案

安全阀。它会让你设置任意的属性为你需要的任何值。以下示例参见此文档：

1. 转到HBase服务。


2. 单击配置选项卡。 >选择作用域> RegionServer。
   
3. 选择类别>高级。
   找到HBase服务高级配置代码段（安全阀） site.xml属性，或通过在搜索框中输入它的名字来搜索它。
4. 添加自定义XML（例如）：
   
   $ b

   <属性>
<名称>属性名称< /名称>
<值>属性值< /值>
< / property>

With CDH 5.7.2-1.cdh5.7.2.po.18, I am trying to use Cloudera Manager to configure HBase to use visibility labels and authorizations, as described in the Cloudera Community post below:

Cloudera Manager Hbase Visibility Labels

Using Cloudera Manager, I have successfully updated the values of the following properties:

• hbase.coprocessor.region.classes: Set to org.apache.hadoop.hbase.security.visibility.VisibilityController
• hbase.coprocessor.master.classes: Set to org.apache.hadoop.hbase.security.visibility.VisibilityController
• hbase.security.authorization: Set to true

Unfortunately, for whatever reason, Cloudera Manager doesn't expose the hfile.format.version variable, so I am unable to set it to 3.

When I restart HBase after updating only the three aforementioned variables, errors such as the following appear in the role log:

ERROR org.apache.hadoop.hbase.coprocessor.CoprocessorHost: The coprocessor org.apache.hadoop.hbase.security.visibility.VisibilityController threw java.lang.RuntimeException: A minimum HFile version of 3 is required to persist security labels. Consider setting hfile.format.version accordingly.

I'd love to set hfile.format.version accordingly, but... how would I do that, when it's not exposed in Cloudera Manager? For example, is there some config file on the file system that I can modify? Cloudera Manager has to be getting the current settings from somewhere.

Thanks!

解决方案

Cloudera Manager has a configuration section it calls the Safety Valve for exactly this purpose. It will let you set arbitrary properties to whatever value you need. See this doc for the following example:

1. Go to the HBase service.
2. Click the Configuration tab.
3. Select Scope > RegionServer.
4. Select Category > Advanced.

5. Locate the HBase Service Advanced Configuration Snippet (Safety Valve) for hbase-site.xml property, or search for it by typing its name in the Search box.

6. Add your custom XML (e.g.):

   <property> <name>property-name</name> <value>property-value</value> </property>
