Subject [jira] [Commented] (ACCUMULO-708) Modify ClassLoader to support different applications / multi-tenancy

-------------------------------------

Dave,

An issue with your most recent patch:

{noformat}
Short umask = Short.parseShort(line.trim());
{noformat}

As Keith pointed out, we need base 8, but the default radix used by parseShort is base 10.
Thus, I get the following incorrectly calculated umask set in the config.

{noformat}
umask response: 0022
Umask is: 026
Perm is: 751
{noformat}

Changing that Short.parseShort method call creates the expected output and the tests then
pass.

{noformat}
Short umask = Short.parseShort(line.trim(), 8);
{noformat}

Output:

{noformat}
umask response: 0022
Umask is: 022
Perm is: 755
{noformat}

> I'd like to expand the current classloader to support loading classes from HDFS and different
application contexts. I'll be modifying the ticket as the idea matures.
