I am trying to import a table from mysql to hive and i getting this errors(all 23 errors almost the same).
023-01-09 18:00:15,370 INFO mapreduce.Job: Task Id : attempt_1673252459679_0002_m_000001_0, Status : FAILED Error: java.lang.ClassCastException: java.util.LinkedList cannot be cast to org.apache.hive.hcatalog.mapreduce.InputJobInfo at org.apache.sqoop.mapreduce.hcat.SqoopHCatImportHelper.<init>(SqoopHCatImportHelper.java:88) at org.apache.sqoop.mapreduce.hcat.SqoopHCatImportMapper.setup(SqoopHCatImportMapper.java:45) at org.apache.hadoop.mapreduce.Mapper.run(Mapper.java:143) at org.apache.hadoop.mapred.MapTask.runNewMapper(MapTask.java:800) at org.apache.hadoop.mapred.MapTask.run(MapTask.java:348) at org.apache.hadoop.mapred.YarnChild$2.run(YarnChild.java:178) at java.security.AccessController.doPrivileged(Native Method) at javax.security.auth.Subject.doAs(Subject.java:422) at org.apache.hadoop.security.UserGroupInformation.doAs(UserGroupInformation.java:1878) at org.apache.hadoop.mapred.YarnChild.main(YarnChild.java:172)
the command is:
sqoop import -connect jdbc:mysql://master:3306/*** --username **** --password **** --query "select id,referrer,from_url,landing_page_url,url_title,platform_description,other_params,history from web_chat_text_ems_2019_07 where 1=1 and $CONDITIONS" --hcatalog-database itcast_ods --hcatalog-table web_chat_text_ems_ods -m 10 --split-by id
the versions: sqoop 1.4.7, hadoop 3.3.1 hive4.0.0-alpha-2,mysql8.0.
And use the command
sqoop list-databases -connect jdbc:mysql://master:3306/ --username **** --password ****
is ok.
why have the errors and how to solve it.
thanks
