[jira] [Commented] (SPARK-14663) Parse escape sequences in
spark-defaults.conf
[ https://issues.apache.org/jira/browse/SPARK-14663?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15243244#comment-15243244 ]
Sergey commented on SPARK-14663:
--------------------------------
UPDATE: I have found a different solution for my particular issue (new APIHadoopFile happens to work with zip files even if passed "org.apache.hadoop.mapreduce.lib.input.TextInputFormat", not "com.cotdp.hadoop.ZipFileInputFormat").
However, the issue remains that a value in spark-defaults.conf cannot be set to "\n".

> Key: SPARK-14663
> URL: https://issues.apache.org/jira/browse/SPARK-14663
> Project: Spark
> Issue Type: Bug
> Components: Spark Core
> Affects Versions: 1.6.1
> Reporter: Sergey
>
> I am trying to specify
> spark.hadoop.textinputformat.record.delimiter in spark-defaults.conf, namely, to set it to "\n" (the #10 character). I know how to do it in sc.newAPIHadoopFile, but I'd like to set it in configuration, so I can keep using sc.textFile (because it also works with zipped files).
> However, I can't find a way to accomplish it.
> I have tried
> spark.hadoop.textinputformat.record.delimiter \n
> spark.hadoop.textinputformat.record.delimiter '\n'
> spark.hadoop.textinputformat.record.delimiter "\n"
> spark.hadoop.textinputformat.record.delimiter \\n (that's two slashes and the letter n)
> spark.hadoop.textinputformat.record.delimiter
> (just pressing enter)
> None of them works. I check in sc._conf.getAll(), and none of them gives me the right result.
