当我尝试将hdfs中的csv文件导入hbase时,我尝试使用importtsv工具使用以下命令:
sudo -u cloudera hadoop jar /opt/cloudera/parcels/CDH-5.0.2-1.cdh5.0.2.p0.13/lib/hbase/hbase-server-0.96.1.1-cdh5.0.2.jar importtsv ...
但是,我在这里遇到了例外:

有谁知道这些问题?是因为cloudera的新版CDH5?
答案 0 :(得分:0)
尝试使用hbase jar直接运行它,如下所示:
hbase org.apache.hadoop.hbase.mapreduce.ImportTsv -Dimporttsv.skip.bad.lines = true -Dimporttsv.columns =“$ columns”$ table_name $ file
(如果hbase不在类路径中,则添加完整路径)
我也在使用CDH5,它对我很有用
