Hi
I want to use nfs to save a copy of the data in namenode, and the nfs
dir /mnt/nfs/dfs/ can be read and written. Things seem to be right, but when
i format the hdfs, ERROR common.Storage: Cannot create lock on
/mnt/nfs/dfs/name/in_use.lock occur.
how to solve the problem?
Peng
The problem is fixed after chmod 777 to /user directory. Thanks.
Best Regards,
J.P

Hello Harsh,
Thanks for your suggestion here. I modified the /tmp to 777, and
something different error happens there:

Hi,
I am new to this Hadoop programming. I tried downloading the vm ware
appliance and Eclipse/Hadoop plugin. I got the same error while
configuring the eclipse plugin for Hadoop DFS.
I started by configuring the VM Ware server formation; entered the IP
address that appeared in the appliance.
Are there any good frameworks for performing and perhaps visualizing
global optimization such as simulated annealing?
One solution i am thinking is lets say you have Kafka or some JMS
implementation where your job client is subscribed to and submits job
dynamically based on queue input size. You may need to run final job to combine
them all.

If you have Serde or PigLoader for your log format, probably Pig or Hive will
be a quicker solution with the join.

I found that Hadoop 0.20.2 and eclipse Helios can work correctly.
It's really hard to make them work together properly.

Bharath,
how would a Pig query look like?
Thank you,

SQL:
SELECT * FROM LOG1 LEFT OUTER JOIN LOG2 ON LOG1.recordid = LOG2.recordid;
PIG:
data = JOIN LOG1 BY recordid LEFT OUTER, LOG2 BY recordid;
DUMP data;
If you need more PIG help, please post in PIG email alias.
