--------------------------------------
Marked as a blocker since this is a regression
> LOAD DATA INPATH doesn't work if hdfs conf includes port
> --------------------------------------------------------
>
> Key: SPARK-25738
> URL: https://issues.apache.org/jira/browse/SPARK-25738
> Project: Spark
> Issue Type: Bug
> Components: SQL
> Affects Versions: 2.4.0
> Reporter: Imran Rashid
> Priority: Blocker
>
> LOAD DATA INPATH throws {{java.net.URISyntaxException: Malformed IPv6 address
> at index 8}} if your hdfs conf includes a port for the namenode.
> This is because the URI is passing in the value of the hdfs conf
> "fs.defaultFS" in for the host. Note that variable is called {{authority}},
> but the 4-arg URI constructor actually expects a host:
> https://docs.oracle.com/javase/7/docs/api/java/net/URI.html#URI(java.lang.String,%20java.lang.String,%20java.lang.String,%20java.lang.String)
> {code}
> val defaultFSConf =
> sparkSession.sessionState.newHadoopConf().get("fs.defaultFS")
> ...
> val newUri = new URI(scheme, authority, pathUri.getPath, pathUri.getFragment)
> {code}
> https://github.com/apache/spark/blob/master/sql/core/src/main/scala/org/apache/spark/sql/execution/command/tables.scala#L386
> This was introduced by SPARK-23425.
> *Workaround*: specify a fully qualified path, eg. instead of
> {noformat}
> LOAD DATA INPATH '/some/path/on/hdfs'
> {noformat}
> use
> {noformat}
> LOAD DATA INPATH 'hdfs://fizz.buzz.com:8020/some/path/on/hdfs'
> {noformat}
