報錯：Move from: hdfs://XXX to: hdfs://YYY is not valid.Please check that values for params "default.fs.name" and "hive.metastore.warehouse.dir" do not conflict.
ERROR tool.ImportTool: Encountered IOException running import job: java.io.IOException: Hive exited with status 44
原因：hive表的location和default.fs.name不一致造成的，
查看location：desc extended hivetablename
查看default.fs.name：在hadoop安裝目錄下core-site.xml文件
將hive表的location 改成fs.default.name的值
修改hive表location ： alter table hivetablename set location 'hdfs://10.100.111.1:9000/user/hive/warehouse/log/hivetablename ';
如果報org.apache.hadoop.mapred.FileAlreadyExistsException: Output directory XXX already exists ，要刪除XXX，在HDFS /user/hadoop/目錄下
hadoop fs -rmr /user/hadoop/XXX
