Hi Thejas M Nair, One question regarding the "fs.permissions.umask-mode". Looks like "fs.permissions.umask-mode" doesn't exist in Hadoop 1.x and property "dfs.umaskmode" is used instead in 1.x for the same purpose. Also "dfs.umaskmode" was not deprecated in 1.x according to
HADOOP-8727. Should we use FsPermission.UMASK_LABEL instead of "fs.permissions.umask-mode" which always points to proper property in latest Hadoop in each version (0.23.x, 1.x, 2.x)?
Attached a testcase to illustrate the problem. Test passes fine with -Phadoop-2, but not with -Phadoop-1.
