-------------------------------
Assignee: vinoyang
> Paths initialized with URI are not normalized
> ---------------------------------------------
>
> Key: FLINK-9527
> URL: https://issues.apache.org/jira/browse/FLINK-9527
> Project: Flink
> Issue Type: Bug
> Components: Core
> Affects Versions: 1.0.3, 1.1.4, 1.2.1, 1.3.3, 1.5.0, 1.4.2, 1.6.0
> Reporter: Chesnay Schepler
> Assignee: vinoyang
> Priority: Major
>
> The {{Path}} class has a lot of logic to normalize paths, like removing
> trailing slashes.
> However, all this normalization can be circumvented by passing in a {{URI}},
> where no normalization is done. I guess this was done on the assumption that
> the normalization was compatible with {{URI}}, but it turns out that this is
> not the case in the case of trailing slashes.
> An {{URI}} may have a trailing slash for directories, whereas a normalized
> {{Path}} does not.
> Unfortunately this breaks some assumptions made in the {{Path}} class, in
> particular {{Path#getParent()}} does not properly handle this case.
> Both assertions in the code below will fail.
> {code}
> public void testPathNormalization() {
> String path = "C:/Users/Zento/AppData/Local/Temp/test/";
> URI uri = URI.create(path);
> Path normalizedPath = new Path(path);
> Path uriPath = new Path(uri);
> Assert.assertEquals(normalizedPath.toString(),
> uriPath.toString());
> Assert.assertEquals("C:/Users/Zento/AppData/Local/Temp",
> uriPath.getParent().getPath());
> }
> {code}
