[jira] [Updated] (HADOOP-15217)
org.apache.hadoop.fs.FsUrlConnection does not handle paths with spaces
[ https://issues.apache.org/jira/browse/HADOOP-15217?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Joseph Fourny updated HADOOP-15217:
-----------------------------------
Description:
When _FsUrlStreamHandlerFactory_ is registered with _java.net.URL_ (ex: when Spark is initialized), it breaks URLs with spaces (even though they are properly URI-encoded). I traced the problem down to _FSUrlConnection.connect()_ method. It naively gets the path from the URL, which contains encoded spaces, and pases it to _org.apache.hadoop.fs.Path(String)_ constructor. This is not correct, because the docs clearly say that the string must NOT be encoded. Doing so causes double encoding within the Path class (ie: %20 becomes %2520).
See attached JUnit test.
