hadoop - 无法使用 importtsv 将数据从 Hdfs 导入到 Hbase

Question

我将制表符分隔的文件移动到 hdfs，现在正试图将它移动到 hbase。 下面是我的 importtsv 命令

  bin/hbase org.apache.hadoop.hbase.mapreduce.ImportTsv -Dimporttsv.columns=HBASE_ROW_KEY,cf:ok,cf:ek,cf:rk,cf:rsk,cf:pdk,cf:pmk,cf:omk,cf:sok,cf:sdk,cf:cdk,cf:q,cf:uc,cf:up,cf:usp,cf:gm,cf:st,cf:gp -Dimporttsv.skip.bad.lines=false 'sales_fact' hdfs://localhost:54310/my/file.txt

它正在尝试从不存在的位置读取一个 jar。

Exception in thread "main" java.io.FileNotFoundException: File does not exist: hdfs://localhost:54310/home/elijah/Downloads/hbase/lib/htrace-core-3.1.0-incubating.jar

我不明白为什么它将 hdfs 和本地目录路径混为一谈。 hdfs://localhost:54310/home/elijah/Downloads/hbase/lib/htrace-core-3.1.0-incubating.jar

运行导入作业的用户对本地目录中的 hbase 库具有完全访问权限。

我可以看到缺少 -libjars 选项....您可以使用 -libjars 选项，下面是示例用法:

hadoop jar \
hbase-server-0.98.6-cdh5.2.1.jar \
importtsv \
-libjars /opt/cloudera/parcels/CDH-5.2.1-1.cdh5.2.1.p0.12/jars/high-scale-lib-1.1.1.jar \
-Dimporttsv.separator=, -Dimporttsv.bulk.output=output \
-Dimporttsv.columns=HBASE_ROW_KEY,f:count wordcount \
word_count.csv

你也可以这样做:-

# export HADOOP_CLASSPATH=`./hbase classpath`

缺少的 jar 之一，即 hbase/lib/htrace-core-3.1.0-incubating.jar 将是 hbase 类路径。并且应该在这种情况下工作。
