Hi Pavel,
Try this:
strace -o output.trace -f hadoop fs -put ... etc ...
then grep clone output.trace

Hi Todd,
java is running as:
/usr/lib/jvm/icedtea6-bin/bin/java <...> -Xmx1000m <...> -Xmx512 <...>
-Xmx512 <...>
(don't know why several Xmx params are used, i thought that last one is
only meaningful).
hadoop-env.sh is:
http://pastebin.com/m544f5b20
~2500MB is available on each VPS node (16G on host machine).
Thank you for answer.

Hi Pavel,
Any chance you've changed the memory settings in hadoop-env.sh to give
absurdly large heap sizes?
How much RAM is available on your machine?

Hello.
I am using hadoop-0.20.1 on two VPS nodes with gentoo linux (hardware
=
16
xeon cpu, 64bit). Previously i was using the same version on 2
separated
32-bit machines and all was fine. Seems to be hadoop can not execute
'whoami'. Maybe reason is another, but hadoop tells me that my name is
"DrWho". For example:
had...@hadoopmaster ~ $ hadoop-0.20.1/bin/hadoop fs -put
/tmp/idata/bigbigbigfile /
put: org.apache.hadoop.security.AccessControlException: Permission
denied:
user=DrWho, access=WRITE, inode="":hadoop:hadoop:rwxr-xr-x
had...@hadoopmaster ~ $
'whoami' itself is available as user 'hadoop' and returns 'hadoop'.
Thank you for any suggestions!
Pavel Kolodin.
