在Alluxio上跑Impala

Question

因为是新手，无法新建标签，所以使用了Alluxio的旧称tachyon作为标签。

---

尝试配置Impala使用Alluxio进行文件操作，失败了。
下面是Impala的配置：

/etc/impala/conf/core-site.xml(http://www.alluxio.org/docs/1...

<configuration>
    <property>
      <name>fs.alluxio.impl</name>
      <value>alluxio.hadoop.FileSystem</value>
      <description>The Alluxio FileSystem (Hadoop 1.x and 2.x)</description>
    </property>
    <property>
      <name>fs.AbstractFileSystem.alluxio.impl</name>
      <value>alluxio.hadoop.AlluxioFileSystem</value>
      <description>The Alluxio AbstractFileSystem (Hadoop 2.x)</description>
    </property>
</configuration>

/etc/impala/conf/hive-site.xml(http://www.alluxio.org/docs/1...

<property>
   <name>fs.defaultFS</name>
   <value>alluxio://192.168.1.10:19998/</value>
</property>

然后启动impala(impala-server, impala-catalogd, impala-state-store), 在impala日志中出现下面的内容，impalad启动失败:

...impala-server.cc:282] Currently configured default file system: FileSystem. fs.defaultFS (alluxio://192.168.1.10:19998/) is not supported.
...impala-server.cc:285] Aborting Impala Server startup due to improper configuration. Impalad exiting.

测试环境中的impala版本: 2.10.0-cdh5.13.0 RELEASE, Alluxio版本: alluxio-1.8.0-hadoop-2.7

在网上搜索了很久，有用的信息很少。有谁尝试过在alluxio上跑Impala吗？谢谢帮助！

Answer 2

CDH 中
Impala Service Environment Advanced Configuration Snippet (Safety Valve)
添加
AUX_CLASSPATH=/path/to/alluxio-2.0.0-client.jar:${AUX_CLASSPATH}

however
只能读和建表，无法插入数据
数据只能从hive插入
