我在 Ubuntu 16.10 上有一个 Hadoop 版本
Hadoop 3.0.0-alpha1
Source code repository https://git-wip-us.apache.org/repos/asf/hadoop.git -r a990d2ebcd6de5d7dc2d3684930759b0f0ea4dc3
Compiled by andrew on 2016-08-30T07:02Z
Compiled with protoc 2.5.0
From source with checksum f3a9644139eac17acbb91bfce7f68e2
This command was run using /home/hduser/hadoop/share/hadoop/common/hadoop-common-3.0.0-alpha1.jar
安装 Hive 2.1.1 后
#Hive environment
export HIVE_HOME=/home/hduser/hive
export PATH=$PATH:$HIVE_HOME/bin
export CLASSPATH=$CLASSPATH:/home/hduser/Hadoop/lib/*:.
export CLASSPATH=$CLASSPATH:/home/hduser/hive/lib/*:.
配置单元环境变量
export HADOOP_HOME=/home/hduser/hadoop
和 db-derby-10.13.1.1。
#Derby environment
export DERBY_HOME=/home/hduser/derby
export PATH=$PATH:$DERBY_HOME/bin
export CLASSPATH=$CLASSPATH:$DERBY_HOME/lib/derby.jar:$DERBY_HOME/lib/derbytools.jar
配置 Metastore hive-site.xml
<property>
<name>javax.jdo.option.ConnectionURL</name>
<value>jdbc:derby://localhost:1527/metastore_db;create=true </value>
<description>
jdbc:derby:;databaseName=metastore_db;create=true
JDBC connect string for a JDBC metastore.
To use SSL to encrypt/authenticate the connection, provide database-specific SSL flag in the connection URL.
For example, jdbc:postgresql://myhost/db?ssl=true for postgres database.

</property>
然后尝试运行HIVE,出现错误

哪个版本的 Hive(Derby)可以与 Hadoop 3.0.0 一起使用?如何解决这个问题?
答案1
您有重复的 slf4j 日志记录 jar,您可以删除这个库:
rm -r -f /home/hduser/hive/lib/log4j-slf4j-impl-2.4.1.jar
答案2
我检查了日志中的错误,详细信息如下:
如果你检查相应的源文件。位置路径是 $HIVE_SRC_HOME\shims\common\src\main\java\org\apache\hadoop\hive\shims\ShimLoader.java
,你会发现它是兼容性问题(重点关注代码的注释)。
/**
* Return the "major" version of Hadoop currently on the classpath.
* Releases in the 1.x and 2.x series are mapped to the appropriate
* 0.x release series, e.g. 1.x is mapped to "0.20S" and 2.x
* is mapped to "0.23".
*/
public static String getMajorVersion() {
String vers = VersionInfo.getVersion();
String[] parts = vers.split("\\.");
if (parts.length < 2) {
throw new RuntimeException("Illegal Hadoop Version: " + vers +
" (expected A.B.* format)");
}
switch (Integer.parseInt(parts[0])) {
case 2:
return HADOOP23VERSIONNAME;
default:
throw new IllegalArgumentException("Unrecognized Hadoop major version number: " + vers);
}
}
所以答案是也许你会降级 Hadoop 版本如果你认为可以通过欺骗编译(修改版本)并且 Hadoop 2.x 看起来(实际上是 Hadoop 3.x)可以很好地适配 Hive 2.x,那么你可以尝试一下。
注意,您可能会遇到更多不可思议的问题。
