0) I am running hadoop-0.20.1.
1) Running only dfs (formatting, then "hadoop-0.20.1/bin/start-dfs.sh")
2) When i try to use 1 laptop with os linux + running VirtualBox on it
with the same linux gentoo in VirtualBox, all fine.
3) When i try to use 2 VPS on 16 cpu intel xenon 64bit hardware with the
same gentoo (or close to mine) OS, i am getting a mess with permissions.
For example:
hadoop@hadoopmaster ~ $ hadoop-0.20.1/bin/hadoop fs -put
/tmp/idata/logogenPY_1259491560 /
put: org.apache.hadoop.security.AccessControlException: Permission denied:
user=DrWho, access=WRITE, inode="":hadoop:hadoop:rwxr-xr-x
hadoop@hadoopmaster ~ $
This put command gives this message in namenode's logfile:
http://pastebin.com/m7b9e10df
Namenode's logfile contains this messages at startup:
http://pastebin.com/m72398acb
4) I am sure, that hadoop's java processes running as 'hadoop', user
exists, group exists etc. I am running as 'hadoop' all the processes
(commands).
hadoop@hadoopmaster ~ $ id
uid=1000(hadoop) gid=1003(hadoop) groups=1003(hadoop)
hadoop@hadoopmaster ~ $
5) After starting i can see this:
hadoopmaster ~ # netstat -natp | grep LIST | grep java
tcp6 0 0 :::33657 :::*

tcp6 0 0 :::50010 :::*
