Java 将csv文件导入hbase

我想在hbase中使用csv文件填写mytable:Province。为此，我使用了以下命令：

bin/hbase org.apache.hadoop.hbase.mapreduce.importtsv -Dimport.columns=
HBASE_ROW_KEY,ProvinceINFO:ID, ProvinceINFO:Name Province /usr/data/province.csv

但它给了我一个错误：

Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/hadoop/hbase
/mapreduce
Caused by: java.lang.ClassNotFoundException: org.apache.hadoop.hbase.mapreduce
at java.net.URLClassLoader$1.run(URLClassLoader.java:217)

Could not find the main class: org.apache.hadoop.hbase.mapreduce. Program will exit.

因此，为了解决这个问题，我做了以下工作：

export HADOOP_CLASSPATH=/Desktop/hbase/lib/hbase-client-0.95.0-hadoop2.jar:/Desktop  
/hbase/lib/hbase-common-0.95.0-hadoop2.jar:/Desktop/hbase/lib/hbase-common-0.95.0-
hadoop2-tests.jar:/Desktop/hbase/lib/hbase-examples-0.95.0-hadoop2.jar:/Desktop/hbase
/lib/hbase-hadoop2-compat-0.95.0-hadoop2.jar:/Desktop/hbase/lib/hbase-hadoop-compat-
0.95.0-hadoop2.jar:/Desktop/hbase/lib/hbase-it-0.95.0-hadoop2.jar:/Desktop/hbase
/lib/hbase-it-0.95.0-hadoop2-tests.jar:/Desktop/hbase/lib/hbase-prefix-tree-0.95.0-
hadoop2.jar:/Desktop/hbase/lib/hbase-protocol-0.95.0-hadoop2.jar:$/Desktop/hbase
/lib/hbase-server-0.95.0-hadoop2.jar:$/Desktop/hbase/lib/hbase-server-0.95.0-hadoop2-
tests.jar:/Desktop/hbase/lib/guava-12.0.1.jar:/Desktop/hbase/conf:/Desktop/hbase
/lib/zookeeper-3.4.5.

将hbase.site.xml复制到hadoop/conf

将所有hbase jar文件以及zookeeper.jar和guava.jar复制到hadoop/lib中

并设置

HADOOP\u类路径

和

HBASE\u路径

，如下所示：

export HADOOP_CLASSPATH=/Desktop/hbase/lib/hbase-client-0.95.0-hadoop2.jar:/Desktop  
/hbase/lib/hbase-common-0.95.0-hadoop2.jar:/Desktop/hbase/lib/hbase-common-0.95.0-
hadoop2-tests.jar:/Desktop/hbase/lib/hbase-examples-0.95.0-hadoop2.jar:/Desktop/hbase
/lib/hbase-hadoop2-compat-0.95.0-hadoop2.jar:/Desktop/hbase/lib/hbase-hadoop-compat-
0.95.0-hadoop2.jar:/Desktop/hbase/lib/hbase-it-0.95.0-hadoop2.jar:/Desktop/hbase
/lib/hbase-it-0.95.0-hadoop2-tests.jar:/Desktop/hbase/lib/hbase-prefix-tree-0.95.0-
hadoop2.jar:/Desktop/hbase/lib/hbase-protocol-0.95.0-hadoop2.jar:$/Desktop/hbase
/lib/hbase-server-0.95.0-hadoop2.jar:$/Desktop/hbase/lib/hbase-server-0.95.0-hadoop2-
tests.jar:/Desktop/hbase/lib/guava-12.0.1.jar:/Desktop/hbase/conf:/Desktop/hbase
/lib/zookeeper-3.4.5.

但这并没有改变

请指导我

类名应该是

org.apache.hadoop.hbase.mapreduce.ImportTsv

如何获取和添加？我认为zsxwing的意思是在您使用的.tnx命令中将

org.apache.hadoop.hbase.mapreduce.ImportTsv

更改为

org.apache.hadoop.hbase.mapreduce.ImportTsv

。已更正。但现在错误me:错误：未指定任何列。请使用-Dimporttsv.columns=。。。在hbase中创建表之前，如下所示：创建“省”、“省信息”
