[jira] [Resolved] (SPARK-5192) Parquet fails to parse schema
contains '\r'
[ https://issues.apache.org/jira/browse/SPARK-5192?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Yin Huai resolved SPARK-5192.
-----------------------------
Seems SPARK-6607 resolved it (PR https://github.com/apache/spark/pull/5263). We will check special characters and if we find any, we throw an exception.

> Key: SPARK-5192
> URL: https://issues.apache.org/jira/browse/SPARK-5192
> Project: Spark
> Issue Type: Bug
> Components: SQL
> Affects Versions: 1.2.0
> Environment: windows7 + Intellj idea 13.0.2
> Reporter: cen yuhai
> Priority: Minor
>
> I think this is actually a bug in parquet, when i debuged 'ParquetTestData', i found a exception as below. So i download the source of MessageTypeParser, the funtion 'isWhitespace' do not check for '\r'
> private boolean isWhitespace(String t) {
> return t.equals(" ") || t.equals("\t") || t.equals("\n");
> }
> So I replace all '\r' to work around this issue.
> val subTestSchema =
> """
> message myrecord {
> optional boolean myboolean;
> optional int64 mylong;
> }
> """.replaceAll("\r","")
