    Description

      Operating on / on ChecksumFileSystem throws NPE

      java.lang.NullPointerException
	at org.apache.hadoop.fs.Path.<init>(Path.java:151)
	at org.apache.hadoop.fs.Path.<init>(Path.java:130)
	at org.apache.hadoop.fs.ChecksumFileSystem.getChecksumFile(ChecksumFileSystem.java:121)
	at org.apache.hadoop.fs.ChecksumFileSystem$FsOperation.run(ChecksumFileSystem.java:774)
	at org.apache.hadoop.fs.ChecksumFileSystem.setReplication(ChecksumFileSystem.java:884)

      Internally I observed it for SetPermission but on my Mac LocalFs doesn't let me setPermission on "/", so I reproduced it via SetReplication which goes through the same code path
