[jira] [Created] (HADOOP-8214) make hadoop script recognize a full
set of deprecated commands
make hadoop script recognize a full set of deprecated commands
--------------------------------------------------------------
Key: HADOOP-8214
URL: https://issues.apache.org/jira/browse/HADOOP-8214
Project: Hadoop Common
Issue Type: Improvement
Components: scripts
Affects Versions: 0.23.1
Reporter: Roman Shaposhnik
Assignee: Roman Shaposhnik
Fix For: 0.23.2
bin/hadoop launcher script does a nice job of recognizing deprecated usage and vectoring users towards the proper command line tools (hdfs, mapred). It would be nice if we can take care of the following deprecated commands that don't get the same special treatment:
{noformat}
oiv apply the offline fsimage viewer to an fsimage
dfsgroups get the groups which users belong to on the Name Node
mrgroups get the groups which users belong to on the Job Tracker
mradmin run a Map-Reduce admin client
jobtracker run the MapReduce job Tracker node
tasktracker run a MapReduce task Tracker node
{noformat}
Here's what I propos to do with them:
# oiv -- issue DEPRECATED warning and run hdfs oiv
# dfsgroups -- issue DEPRECATED warning and run hdfs groups
# mrgroups -- issue DEPRECATED warning and run mapred groups
# mradmin -- issue DEPRECATED warning and run yarn rmadmin
# jobtracker -- issue DEPRECATED warning and do nothing
# tasktracker-- issue DEPRECATED warning and do nothing
Thoughts?
