Apache Spark commented on SPARK-25237: -------------------------------------- User 'maropu' has created a pull request for this issue: https://github.com/apache/spark/pull/22324 > FileScanRdd's inputMetrics is wrong when select the datasource table with > limit > -------------------------------------------------------------------------------- > > Key: SPARK-25237 > URL: https://issues.apache.org/jira/browse/SPARK-25237 > Project: Spark > Issue Type: Bug > Components: SQL > Affects Versions: 2.2.2, 2.3.1 > Reporter: du > Priority: Major > > In FileScanRdd, we will update inputMetrics's bytesRead using updateBytesRead > every 1000 rows or when close the iterator. > but when close the iterator, we will invoke updateBytesReadWithFileSize to > increase the inputMetrics's bytesRead with file's length. > this will result in the inputMetrics's bytesRead is wrong when run the query > with limit such as select * from table limit 1. > because we do not support for Hadoop 2.5 and earlier now, we always get the > bytesRead from Hadoop FileSystem statistics other than files's length. > -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
