Hi,

Did a test on recursive chown on a fedora 9 box here (2xquad core,16Gram)
Took about 12.5 minutes to complete for 45000 files. (hmm approx 60 files/sec)

This was the namenode that I executed the command on

Q1. Is this rate (60 files/sec) typical of what other folks are seeing ?
Q2. Are there any dfs/jvm parameters I should look at to see if I can improve 
this

time /home/hadoop/hadoop-0.18.1/bin/hadoop dfs -chown -R frank:frank 
/home/frank/proj100

real    12m38.631s
user    1m54.662s
sys     0m33.124s

time /home/hadoop/hadoop-0.18.1/bin/hadoop dfs -count /home/frank/proj100
         220        45891         3965996260 
hdfs://namenode:9000/home/frank/proj100

real    0m1.579s
user    0m0.686s
sys     0m0.129s


cheers / frank
