How to resolve Talend Parquet /HDFS schema incompatibilities
convert all columns to String all your columns, make sure he schema are exactly the same including ( actually what you’re writting to Parquet is a string whatever the format you specify)
Replace all null values by “” by creating a tReplace component that do this conversion for all strings
PS : for those who uses Tableau plugged on Parquet tables, don’t worry much about formats , Tableau detect automatically the type of the columns, ie. a date is converted to Date in Tableau even if it’s specified as String in Parquet.
