Vinod K V commented on HADOOP-4491:
-----------------------------------
I had some offline discussions with Hemanth/Owen/Arun. Those discussions
resulted in a change of proposal for this JIRA.
The TaskTracker's directory structure will be like the following:
{noformat}
$ttroot
|
|- distcache
|
|- users
| |
| '-- $jobid
| |
| |- jars
| | '-- job.jar
| |- work
| |
| `-- $attemptid
| |- job.xml
| |- taskjvm.sh
| |- work
| | '-- tmp
| `-- output
|
'-- system
|
`-- $jobid
|
|- job.xml
|
|- userfiles
| |- jars
| | '-- job.jar
| '-- work
|
|- $attemptid
| |- job.xml
| |- taskjvm.sh
| '-- work
| '-- tmp
|
'-- outputs
`-- $attemptid
{noformat}
> Per-job local data on the TaskTracker node should have right access-control
