Apache Spark reassigned SPARK-17159: ------------------------------------ Assignee: Apache Spark > Improve FileInputDStream.findNewFiles list performance > ------------------------------------------------------ > > Key: SPARK-17159 > URL: https://issues.apache.org/jira/browse/SPARK-17159 > Project: Spark > Issue Type: Improvement > Components: Streaming > Affects Versions: 2.0.0 > Environment: spark against object stores > Reporter: Steve Loughran > Assignee: Apache Spark > Priority: Minor > > {{FileInputDStream.findNewFiles()}} is doing a globStatus with a fitler that > calls getFileStatus() on every file, takes the output and does listStatus() > on the output. > This going to suffer on object stores, as dir listing and getFileStatus calls > are so expensive. It's clear this is a problem, as the method has code to > detect timeouts in the window and warn of problems. > It should be possible to make this faster -- 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
