Karen Yin-Yee Ng commented on SPARK-9807: ----------------------------------------- It just means that the DataFrame keeps the data type from the RDD. It has not done any type inference from a user's perspective. > pyspark.sql.createDataFrame does not infer data type of parsed TSV > ------------------------------------------------------------------ > > Key: SPARK-9807 > URL: https://issues.apache.org/jira/browse/SPARK-9807 > Project: Spark > Issue Type: Bug > Components: PySpark > Affects Versions: 1.4.1 > Environment: CentOS 6, Python version 2.7.10, Scala version 2-10 > Reporter: Karen Yin-Yee Ng > Original Estimate: 24h > Remaining Estimate: 24h > > I tried parsing a space-separated file from HDFS. > And using `pyspark.sqlContext.createDataFrame` to convert the parsed lines to > a PySpark DataFrame. However, all entries are parsed as string type > regardless of what the correct data type is. > An example of my code and output can be found at: > https://gist.github.com/karenyyng/a1264d6344c54df4fcc5 -- 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
