I am not aware of a direct regression in DN startup slowdown or block
report slowdown; its hard to tell what exactly the regression is without
more notes or logs on behavior.

Hello Varun,
Thank you so much for your reply. In most of the
cases, it is not. But apart from that everything seems
to be fine. I am not getting any notification about
under replicated blocks or corrupted blocks. I will do
a recheck though.
Thank you.
Warm Regards,
Tariq

Thank you so much for the valuable reply Harsh. I'll
look into it. One quick question, why it it happening
with 1.0.4? Is there any compulsion to set these two
props, you have specified above. Earlier version were
doing absolutely fine without these props?
I am Sorry to be a pest of questions. But
Hi Tariq,
When you start your namenode,Is it able to come out of Safemode
Automatically.
If no then there are under replicated blocks or corrupted blocks where
namenode is trying to fetch it.
Try to remove corrupted blocks.

If your DN is starting too slow, then you should investigate why.
In any case, Apache Bigtop's (http://bigtop.apache.org) pseudo-distributed
configs provide good values for 1-node setups. In your case, you seem to be
missing dfs.safemode.min.datanodes set to 1, and dfs.safemode.extension set
to 0.
Check integrity of the file system, and check the replication factor, by
mistake if default is left as 3 or so. if you have hbase configured check
hbck if everything is fine with the cluster.

Hey Jean,
Feels good to hear that ;) I don't have to feel
myself a solitary yonker anymore.
Since I am working on a single node, the problem
becomes more sever. I don't have any other node
where MR files could get replicated.

Hi Tariq,
I often have to force HDFS to go out of safe mode manually when I
restart my cluster (or after power outage) I never tought about
reporting that ;)
I'm using hadoop-1.0.3. I think it was because of the MR files still
not replicated on enought nodes. But not 100% sure.
