Keith Turner commented on ACCUMULO-708:
---------------------------------------
I modified the commented out code that was trying to set the persmissions and I
think I have that working. The existing code was dealing with base 10 numbers
instead of base 8. In java prefixing a number with 0 makes it base 8, so it
needs to be 0777 instead of 777. Also need to format the result as base 8
instead of base 10. Could have changed Intereger.toString(newPermission) to
Integer.toString(newPermission, 8) but I used string.format instead.
{code:java}
//HDFS-1560
//Need to set permission to 777 xor umask
FsPermission fsp = FsPermission.getUMask(conf);
short umask = fsp.toShort();
// leading zero makes java interpret as base 8
int newPermission = 0777 ^ umask;
conf.set("dfs.datanode.data.dir.perm", String.format("%03o",
newPermission));
{code}
