Reynold Xin created SPARK-18760:
-----------------------------------
Summary: Provide consistent format output for all file formats
Key: SPARK-18760
URL: https://issues.apache.org/jira/browse/SPARK-18760
Project: Spark
Issue Type: New Feature
Components: SQL
Reporter: Reynold Xin
Assignee: Reynold Xin
We currently rely on FileFormat implementations to override toString in order
to get a proper explain output. It'd be better to just depend on shortName for
those.
Before:
{noformat}
scala> spark.read.text("test.text").explain()
== Physical Plan ==
*FileScan text [value#15] Batched: false, Format:
org.apache.spark.sql.execution.datasources.text.TextFileFormat@xyz, Location:
InMemoryFileIndex[file:/scratch/rxin/spark/test.text], PartitionFilters: [],
PushedFilters: [], ReadSchema: struct<value:string>
{noformat}
After:
{noformat}
scala> spark.read.text("test.text").explain()
== Physical Plan ==
*FileScan text [value#15] Batched: false, Format: text, Location:
InMemoryFileIndex[file:/scratch/rxin/spark/test.text], PartitionFilters: [],
PushedFilters: [], ReadSchema: struct<value:string>
{noformat}
