Jordan Sissel commented on HADOOP-6876:
---------------------------------------
Updated my own code and confirmed that my suggested workaround does work.
> Path.suffix(...) on a path url with no "path" results in NullPointerException
> -----------------------------------------------------------------------------

> Key: HADOOP-6876
> URL: https://issues.apache.org/jira/browse/HADOOP-6876
> Project: Hadoop Common
> Issue Type: Bug
> Affects Versions: 0.20.2
> Reporter: Jordan Sissel
>
> I can most briefly demo this using the hbase jruby shell (as it has hadoop in
> the classpath:
> {noformat}
> hbase(main):001:0> path = org.apache.hadoop.fs.Path.new("hdfs://testing/")
> => #<Java::OrgApacheHadoopFs::Path:0x6128453c
> @java_object=#<Java::JavaObject:0x1ad997f9>>
> hbase(main):002:0> path.suffix("Test")
> NativeException: java.lang.NullPointerException: null
> {noformat}
> I expected instead that path.suffix("Test") would simply generate a new path
> with 'Test' appended. For above, this would be the path "hdfs://testing/Test"
> Workaround: This should work - instead of using path.suffix(), use this
> (java):
> {noformat}
> Path newpath = new Path(oldpath.toString() + "mysuffix");
> {noformat}
