Outputs on trunk as of today:
1.
{code:java}
Path path = new Path("file:///something").suffix("else");
System.out.println(path);
{code}
output:
{code:java}
file:/somethingelse{code}
2.
{code:java}
Path path = new Path("/something").suffix("else");
System.out.println(path);
{code}
output:
{code:java}
/somethingelse{code}
was (Author: vjasani):
On trunk, with scheme, suffix is producing NPE:
{code:java}
new Path("file://something").suffix("else")
{code}
output:
{code:java}
java.lang.NullPointerException
at org.apache.hadoop.fs.Path.<init>(Path.java:152)
at org.apache.hadoop.fs.Path.<init>(Path.java:130)
at org.apache.hadoop.fs.Path.suffix(Path.java:468)
{code}
However, this seems to be working fine:
{code:java}
Path path = new Path("/something").suffix("else");
System.out.println(path);
{code}
output:
{code:java}
/somethingelse{code}
> Path.suffix() raises an exception when the path is in the root dir
