Suresh Srinivas updated HDFS-1547:
----------------------------------
Attachment: HDFS-1547.patch
In addition to the proposed changes I made the following changes:
> In Live Nodes web page, in addition to live nodes listed today, a separate
> table (not column) will list decommissioned nodes.
I noticed that there is a column already in live nodes table that lists admin
state. I made it sortable to find the decommissioned nodes, instead of adding a
new table.
# In Dead Nodes web page, in addition to live nodes listed today, a separate
table (not column) will list decommissioned nodes.
I added a colum that indicates if the node is decommissioned (true/false). It
is sortable.
The reason for not adding a separate table is, it make sorting tables confusing
and the existing jsp page more complicated.
Other changes:
# Added decommissioned state to JMX methods FSNameSystem#getLiveNodes() and
FSNameSystem#getDeadNodes()
# Changed the DFSAdmin command to fix incorrect explanation of include/exclude
file.
# Update DFSAdmin -refreshNodes document the new behavior.
> Improve decommission mechanism
