Create Hive table to read parquet files from parquet/avro schema

问题

We are looking for a solution in order to create an external hive table to read data from parquet files according to a parquet/avro schema.

in other way, how to generate a hive table from a parquet/avro schema ?

thanks :)

Try below using avro schema:

CREATE TABLE avro_test ROW FORMAT SERDE 'org.apache.hadoop.hive.serde2.avro.AvroSerDe' STORED AS AVRO TBLPROPERTIES ('avro.schema.url'='myHost/myAvroSchema.avsc'); 

CREATE EXTERNAL TABLE parquet_test LIKE avro_test STORED AS PARQUET LOCATION 'hdfs://myParquetFilesPath';
