Question

我使用HDP3.1。我Ambari部署了hadoop集群和配置单元。部署后，我可以在Shell中成功运行配置单元。然后我部署Apache Kylin2.6，它可以同步配置单元表。但是当我构建多维数据集时，出现以下错误：

java.io.IOException: OS command error exit with return code: 1, error message: SLF4J: Class path contains multiple SLF4J bindings.

The command is:

我在shell中运行hive命令。成功了连接字符串与在kylin中运行build cube时的字符串相同。我很困惑为什么它在shell中成功但是在构建多维数据集时失败。

Answer 1

您可以尝试将这两个属性添加到hive-site.xml。

<property>
  <name>hive.security.authorization.sqlstd.confwhitelist</name>
  <value>mapred.*|hive.*|mapreduce.*|spark.*</value>
</property>

<property>
  <name>hive.security.authorization.sqlstd.confwhitelist.append</name>
  <value>mapred.*|hive.*|mapreduce.*|spark.*</value>
</property>

Answer 2

Finally, I found the root cause. There is 'Cannot modify dfs.replication at runtime.' error message in the error log. Kylin set this property in $KYLIN_HOME/conf/kylin_hive_conf.xml. And when it is running hive command, it will auto append the properties in that file. The final command likes: hive --hiveconf dfs.replication=2 ..........
It looks like that dfs.replication property can't be appened to hive command. I removed this property in kylin_hive_conf.xml. And it works now.

无法从ZooKeeper读取HiveServer2配置
