[jira] [Updated] (SPARK-3276) Provide a API to specify whether the
old files need to be ignored in file input text DStream
[ https://issues.apache.org/jira/browse/SPARK-3276?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Sean Owen updated SPARK-3276:
-----------------------------
Priority: Minor (was: Major)
Affects Version/s: (was: 1.0.2)
1.2.0
Issue Type: Improvement (was: Bug)
So is the request here to just add this flag to the textFileStream method too? I agree that this sounds like the goal and you can accomplish this right now with a line of code in the current API too.

> Key: SPARK-3276
> URL: https://issues.apache.org/jira/browse/SPARK-3276
> Project: Spark
> Issue Type: Improvement
> Components: Streaming
> Affects Versions: 1.2.0
> Reporter: Jack Hu
> Priority: Minor
>
> Currently, only one API called textFileStream in StreamingContext to specify the text file dstream, which ignores the old files always. On some times, the old files is still useful.
> Need a API to let user choose whether the old files need to be ingored or not .
> The API currently in StreamingContext:
> def textFileStream(directory: String): DStream[String] = {
> fileStream[LongWritable, Text, TextInputFormat](directory).map(_._2.toString)
> }
