hive 是Hadoop中最常用的工具,可以说是必装工具。
按apache官方文档,推荐使用svn下载后编译,文档地址:https://cwiki.apache.org/confluence/display/Hive/AdminManual+Installation
但build时,因为依赖关系,整了很久,下了很多包也没有成功。
推荐使用tar.gz包,直接安装,文档地址:https://cwiki.apache.org/confluence/display/Hive/GettingStarted#GettingStarted-InstallationandConfiguration
很简单,直接成功!
首次运行hive时报错:
Exception in thread "main" java.lang.NoSuchFieldError: ALLOW_UNQUOTED_CONTROL_CHARS at org.apache.hadoop.hive.ql.udf.generic.GenericUDTFJSONTuple.<clinit>(GenericUDTFJSONTuple.java:59) at sun.reflect.NativeConstructorAccessorImpl.newInstance0(Native Method) at sun.reflect.NativeConstructorAccessorImpl.newInstance(NativeConstructorAccessorImpl.java:39) at sun.reflect.DelegatingConstructorAccessorImpl.newInstance(DelegatingConstructorAccessorImpl.java:27) at java.lang.reflect.Constructor.newInstance(Constructor.java:513) at org.apache.hadoop.util.ReflectionUtils.newInstance(ReflectionUtils.java:113) at org.apache.hadoop.hive.ql.exec.FunctionRegistry.registerGenericUDTF(FunctionRegistry.java:545) at org.apache.hadoop.hive.ql.exec.FunctionRegistry.registerGenericUDTF(FunctionRegistry.java:539) at org.apache.hadoop.hive.ql.exec.FunctionRegistry.<clinit>(FunctionRegistry.java:472) at org.apache.hadoop.hive.ql.session.SessionState.<init>(SessionState.java:202) at org.apache.hadoop.hive.cli.CliSessionState.<init>(CliSessionState.java:86) at org.apache.hadoop.hive.cli.CliDriver.run(CliDriver.java:635) at org.apache.hadoop.hive.cli.CliDriver.main(CliDriver.java:613) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:597) at org.apache.hadoop.util.RunJar.main(RunJar.java:156)
ALLOW_UNQUOTED_CONTROL_CHARS是关键字
原因:
hive 里的 jackson jar 包 和 hadoop 里的不一致, hadoop 里的用的是老的 1.0.1 的, hive 里的是 1.8.8.
将hadoop 里的jar 替换成和 hive 一样的就ok了,
找不到jar包的可以find一下。
