------------------------------------
Updated ticket description to provide a more general view of this issue. Would
also be helpful for reviewing https://github.com/apache/spark/pull/8509
> For struct type, if parquet's global schema has less fields than a file's
> schema, data reading will fail
> --------------------------------------------------------------------------------------------------------
>
> Key: SPARK-10301
> URL: https://issues.apache.org/jira/browse/SPARK-10301
> Project: Spark
> Issue Type: Bug
> Components: SQL
> Affects Versions: 1.5.0
> Reporter: Yin Huai
> Assignee: Cheng Lian
> Priority: Critical
>
> We hit this issue when reading a complex Parquet dateset without turning on
> schema merging. The data set consists of Parquet files with different but
> compatible schemas. In this way, the schema of the dataset is defined by
> either a summary file or a random physical Parquet file if no summary files
> are available. Apparently, this schema may not containing all fields
> appeared in all physicla files.
> Parquet was designed with schema evolution and column pruning in mind, so it
> should be legal for a user to use a tailored schema to read the dataset to
> save disk IO. For example, say we have a Parquet dataset consisting of two
> physical Parquet files with the following two schemas:
> {noformat}
> message m0 {
> optional group f0 {
> optional int64 f00;
> optional int64 f01;
> }
> }
> message m1 {
> optional group f0 {
> optional int64 f01;
> optional int64 f01;
> optional int64 f02;
> }
> optional double f1;
> }
> {noformat}
> Users should be allowed to read the dataset with the following schema:
> {noformat}
> message m1 {
> optional group f0 {
> optional int64 f01;
> optional int64 f02;
> }
> }
> {noformat}
> so that {{f0.f00}} and {{f1}} are never touched. The above case can be
> expressed by the following {{spark-shell}} snippet:
> {noformat}
> import sqlContext._
> import sqlContext.implicits._
> import org.apache.spark.sql.types.{LongType, StructType}
> val path = "/tmp/spark/parquet"
> range(3).selectExpr("NAMED_STRUCT('f00', id, 'f01', id) AS f0").coalesce(1)
> .write.mode("overwrite").parquet(path)
> range(3).selectExpr("NAMED_STRUCT('f00', id, 'f01', id, 'f02', id) AS f0",
> "CAST(id AS DOUBLE) AS f1").coalesce(1)
> .write.mode("append").parquet(path)
> val tailoredSchema =
> new StructType()
> .add(
> "f0",
> new StructType()
> .add("f01", LongType, nullable = true)
> .add("f02", LongType, nullable = true),
> nullable = true)
> read.schema(tailoredSchema).parquet(path).show()
> {noformat}
> Expected output should be:
> {noformat}
> +--------+
> | f0|
> +--------+
> |[0,null]|
> |[1,null]|
> |[2,null]|
> | [0,0]|
> | [1,1]|
> | [2,2]|
> +--------+
> {noformat}
> However, current 1.5-SNAPSHOT version throws the following exception:
> {noformat}

> This issue can be generalized a step further. Taking interoperability into
> consideration, we may have a Parquet dataset consisting of physical Parquet
> files sharing compatible logical schema, but created by different Parquet
> libraries. Because of the historical nested type compatibility issue,
> physical Parquet schemas generated by different by those libraries may be
> different. It would be nice to be able to operate on such datasets.
