What Are the Data Types Allowed with the Sqoop Option "--Map-Column-Java"?

It's pretty taught to load from database into parquet through sqoop, keeping the source datatypes, from the datatypes point of view. For example, you can't load timestamp because it's not supported.

I'm suggesting you the next workaround:

1. Load with sqoop with all the datatypes string;
2. Insert from table 1 (with all the datatypes string) into table 2, using cast (as timestamp, as decimal ... etc);

Example:

--map-column-java "ID=String,NR_CARD=String,TIP_CARD_ID=String,CONT_CURENT_ID=String,AUTORIZ_CONTURI_ID=String,TIP_STARE_ID=String,DATA_STARE=String,COMIS=String,BUGETARI_ID=String,DATA_SOLICITARII=String,DATA_EMITERII=String,DATA_VALABILITATII=String,TIP_DESCOPERIT_ID=String,BRANCH_CODE_EMIT=String,ORG_ID=String,DATA_REGEN=String,FIRMA_ID=String,VOUCHER_BLOC=String,CANAL_CERERE=String,CODE_BUG_OPER=String,CREATED_BY=String,CREATION_DATE=String,LAST_UPDATED_BY=String,LAST_UPDATE_DATE=String,LAST_UPDATE_LOGIN=String,IDPAN=String,MOTIV_STARE_ID=String,DATA_ACTIVARII=String" \

In this way you will have all the datatypes, correctly loaded from source.
