问题:
我正在使用文档中的这个示例尝试从文本文件将数据导入hbase数据库。
配置
hbase版本: hbase-0.94.4
.
我的安装是 Standalone
(非分布式或伪分布式)。
再现误差
最初,它在hdfs上创建storefiles,并创建一个名为 datatsv
,使用:
HADOOP_CLASSPATH=`${HBASE_HOME}/bin/hbase classpath` ${HADOOP_HOME}/bin/hadoop \
jar /usr/local/hbase/hbase-0.94.4.jar importtsv \
-Dimporttsv.columns=HBASE_ROW_KEY,d:c1,d:c2 \
-Dimporttsv.bulk.output=/user/vm1/outputfile datatsv /user/vm1/myfile.txt
然后,completebulkload方法将数据从storefile加载到表:
hbase org.apache.hadoop.hbase.mapreduce.LoadIncrementalHFiles \
/user/vm1/outputfile datatsv
以下命令与上面的命令具有相同的输出:
HADOOP_CLASSPATH=`${HBASE_HOME}/bin/hbase classpath` ${HADOOP_HOME}/bin/hadoop \
jar /usr/local/hbase/hbase-0.94.4.jar completebulkload \
/user/vm1/outputfile datatsv
任一命令的错误消息为:

问题
我遗漏了什么吗?
搜索邮件列表,在免费节点上询问,但没有找到答案。还尝试使用以下方法设置hbase的属性(并重新启动它): hbase.metrics.showTableName
至 false
任何帮助都将不胜感激!谢谢!

我问的那个工具已经不起作用了。因此,我编写了一些java代码,使用hbase api使用mapreduce进行批量加载。
github链接:hbase批量加载
lp0sw83n2#
不久前,当我尝试使用javaapi批量加载数据时,遇到了一个非常类似的问题。我在这里打开了一条线。我必须在我的客户机应用程序中指定这一行,这解决了问题:
SchemaMetrics.configureGlobally(conf)
. 现在,您不需要使用JavaAPI,这行所做的只是在.xml配置中设置一个属性,这样您就可以手动设置它了。我想试试这个:hbase.metrics.showTableName
,应该已经true
默认情况下,但我会尝试将其设置为true
明确地。目前我正在开发hbase 0.90(hortonworkshdp1.1附带的版本),我甚至不需要使用它SchemaMetrics.configureGlobally(conf)
不再。可能是hbase 0.94中的一个bug(或者只是一种新方法)?
