error copying file from local to hadoop fs
hi,
I am trying to copy a local text file into hadoop fs using -copyFromLocal
option, but i am getting error:
13/03/29 03:02:54 INFO ipc.Client: Retrying connect to server:

What do you mean with standalone mode?
"standalone" in the sense of hadoop docs uses it means, no daemons are
running. Everything is done locally (local file system, everything in one
JVM).
"pseudo distributed" means, all daemons of hadoop run on a single node.
Network protocols are used for communication.
Assuming "pseudo distributed" is the set-up you use:

In "pseudo distributed" mode, all daemons are expected to run. NameNode,
DataNode, JobTracker, etc.
Check the start-up logs.
Best regards,
Jens

It would appear that your HDFS set up is not functioning properly.
Please try to shut down HDFS (stop-all.sh).. waiting for a bit (5 mins) and
restarting HDFS (start-all.sh).
If that does not work, you might have to reformat the NameNode (after
shutting down HDFS again).

Re: error copying file from local to hadoop fs
Posted by Ravi Chandran <ra...@gmail.com>.
But in standalone mode, should the safemode be faster? I mean because
everything is running locally. still the deamons are not visible in jps.
how can i restart it individually?
also, the service status returned this info:
Hadoop namenode is running [ OK ]
Hadoop secondarynamenode is not running [FAILED]
Is the secondary namenode, not supposed to run in standalone mode? i am not
able to restart this service also.. it just gives unrecognized service.

Hello,
In the Safe Mode, -copyFromLocal would not work.
Please read:
http://hadoop.apache.org/docs/stable/hdfs_user_guide.html#Safemode
Please wait a bit for the HDFS system to exit SafeMode. If it takes a
significantly long time, and the HDFS is still in the SafeMode, something
could be wrong with your HDFS setup.

Re: error copying file from local to hadoop fs
Posted by Anand Aravindan <an...@gmail.com>.
Hello,
In the Safe Mode, -copyFromLocal would not work.
Please read:
http://hadoop.apache.org/docs/stable/hdfs_user_guide.html#Safemode
Please wait a bit for the HDFS system to exit SafeMode. If it takes a
significantly long time, and the HDFS is still in the SafeMode, something
could be wrong with your HDFS setup.

Thanks for replying, I did jps, it doesnt show any of the deamon services.
also, i just got the error message showing:
Cannot create file/user/training/inputs/basic.txt._COPYING_. Name node is
in safe mode.
looks like JT and DN are not responding to NN. but this is a standalone
