Problem Summary:
For the
bitmap
type, doris does not currently support reading, so the previous implementation method is to ignore thebitmap
type field by setting thedoris.ignore-type
option.However, when you import data into Doris by executing the
insert into select
statement, the source table and the target table have the same number of columns, and you need to map the source table columns to columns of the Doris bitmap type, the number of select columns and the number of target table columns will be inconsistent, causing Spark parsing failure.So now the solution is as follows:
bitmap
andHLL
type columns will return the string constant 'READ UNSUPPORTED'.bitmap
andHLL
type columns are converted to bitmap type by specifying function mapping using the doris.write.fields option.doris.ignore-type
option will be removedChecklist(Required)
