Pranav Saxena commented on HADOOP-18580:


AbfsClient#createRequestUrl uses URLEncoder.encode(val, UTF_8).

{code:java}
String val = ".../part=a%25percent/test.parquet";
System.out.println(URLEncoder.encode(val, UTF_8));
{code}

gives:
`...%2Fpart%3Da%2525percent%2Ftest.parquet`

we can do something like:

{code:java}
URLEncoder.encode(val, UTF_8).replace("%2525", "%25")
{code}

so there's some double encoding going on? sounds like a bug

note that azure doesn't like files ending with "."; everything gets to have its 
own quirk
