Cheng Lian updated SPARK-15983: ------------------------------- Summary: Remove FileFormat.prepareRead() (was: Remove FileFormat.prepareRead) > Remove FileFormat.prepareRead() > ------------------------------- > > Key: SPARK-15983 > URL: https://issues.apache.org/jira/browse/SPARK-15983 > Project: Spark > Issue Type: Improvement > Components: SQL > Affects Versions: 2.0.0 > Reporter: Cheng Lian > Assignee: Cheng Lian > > Interface method {{FileFormat.prepareRead()}} was added in [PR > #12088|https://github.com/apache/spark/pull/12088] to handle a special case > in the LibSVM data source. > However, the semantics of this interface method isn't intuitive: it returns a > modified version of the data source options map. Considering that the LibSVM > case can be easily handled using schema metadata inside {{inferSchema}}, we > can remove this interface method to keep the {{FileFormat}} interface clean. -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
