[jira] [Comment Edited] (BEAM-2277) IllegalArgumentException when
using Hadoop file system for WordCount example.
[ https://issues.apache.org/jira/browse/BEAM-2277?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16587202#comment-16587202 ]

--------------------------------------------------------------
Is anyone have this problem if it is using HDFS paths in form with vs without authority? *hdfs:///path/to/dir* vs *hdfs://ha-nn/path/to/dir* ?
I suspect the problem could be drop empty authority here:
[https://github.com/apache/beam/blob/master/sdks/java/io/hadoop-file-system/src/main/java/org/apache/beam/sdk/io/hdfs/HadoopFileSystem.java#L260]
Which does for
{code:java}
FileSystems.matchNewResource("hdfs:///path/to/dir", false)
{code}
produce
{code:java}
hdfs:/path/to/dir
{code}
Reading back such path via FileSystems.matchNewResource() produce a ResourceId with "file" schema because of the chance in BEAM-5180
