我尝试将 Impala 配置为在 Alluxio 之上运行,但失败了。
这是 Impala 配置:
/etc/impala/conf/core-site.xml( http://www.alluxio.org/docs/1.6/en/Running-Hadoop-MapReduce-on-Alluxio.html )
<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/1.6/en/Running-Hive-with-Alluxio.html )
<property>
<name>fs.defaultFS</name>
<value>alluxio://master_hostname:port</value>
</property>
然后我启动了 Impala(impala-server, impala-catalogd, impala-state-store),但是在日志中我发现了这个:
...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.
我在 Bing 上搜索了很多,但没有运气。即使搜索关键字“alluxio 上的黑斑羚”也没有什么结果。那么 impala 可以在 alluxio 之上运行吗?任何建议将不胜感激。
我的 Impala 版本:2.10.0-cdh5.13.0 RELEASE,Alluxio 版本:alluxio-1.8.0-hadoop-2.7
