问题
I am getting a strange error when sqooping the data from oracle DB to HDFS. Sqoop is not able to import clob data into an avro files on hadoop.
This is the sqoop import error :
ERROR tool.ImportTool: Imported Failed: Cannot convert SQL type 2005
Do we need to add any extra arguments to sqoop import statement for it correctly import clob data into avro files ?
回答1:
Update: Found the solution, We need to add --map-column-java for the clob columns.
For Eg: If the column name is clob then we have pass --map-column-java clob=string for sqoop to import the clob columns.
