Eric Liang created SPARK-18725:
----------------------------------
Summary: Creating a datasource table with schema should not scan
all files for table
Key: SPARK-18725
URL: https://issues.apache.org/jira/browse/SPARK-18725
Project: Spark
Issue Type: Bug
Components: SQL
Affects Versions: 2.1.0
Reporter: Eric Liang
When creating an unpartitioned Datasource table, Spark will scan the table for
all files to infer the schema, even if the user already provides a schema.
This is fixed for partitioned tables by
https://github.com/apache/spark/pull/16090 but this was left as a separate
followup. Since unpartitioned tables are not typically large this can probably
be left out of 2.1 release.
