Al M created SPARK-5270: --------------------------- Summary: Elegantly check if RDD is empty Key: SPARK-5270 URL: https://issues.apache.org/jira/browse/SPARK-5270 Project: Spark Issue Type: Improvement Affects Versions: 1.2.0 Environment: Centos 6 Reporter: Al M Priority: Trivial
Right now there is no clean way to check if an RDD is empty. As discussed here: http://apache-spark-user-list.1001560.n3.nabble.com/Testing-if-an-RDD-is-empty-td1678.html#a1679 This is especially a problem when using streams. Sometimes my batches are huge in one stream, sometimes i get nothing for hours. Still I have to run count() to check if there is anything in the RDD. I can also run first() and catch the exception; this is neither a clean nor fast solution. I'd like a method rdd.isEmpty that returns a boolean. -- 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
