Wenchen Fan resolved SPARK-18726. --------------------------------- Resolution: Fixed Fix Version/s: 2.2.0 Issue resolved by pull request 17081 [https://github.com/apache/spark/pull/17081] > Filesystem unnecessarily scanned twice during creation of non-catalog table > --------------------------------------------------------------------------- > > Key: SPARK-18726 > URL: https://issues.apache.org/jira/browse/SPARK-18726 > Project: Spark > Issue Type: Bug > Components: SQL > Affects Versions: 2.1.0 > Reporter: Eric Liang > Fix For: 2.2.0 > > > It seems that for non-catalog tables (e.g. spark.read.parquet(...)), we scan > the filesystem twice, once for schema inference, and another to create a > FileIndex class for the relation. > It would be better to combine these scans somehow, since this is the most > costly step of creating a table.
