Can not generate a result
hi i am new to hadoop.
i already do the the precautionary measures like : configuring hadoop as pseudo-distributed operations, namenode -format etc. before
running start-all.sh
and i try to execute sample program WordCount by using :
./bin/hadoop jar /home/astie/thesis/project_eclipse/WordCount.jar WordCount /home/astie/thesis/project_eclipse/input/ /home/astie/thesis/project_eclipse/output/
it doesn't generate the result and i got this in the log file :
2012-08-13 11:28:27,053 WARN org.apache.hadoop.hdfs.DFSClient: Error Recovery for block null bad datanode[0] nodes == null

i am using openSuse and hadoop-1.0.3 also using eclipse to write the program.
it is said that the node was null. yes, i am still running it with my computer only. is it the problem?
can you tell me how to fix this? thank you

Hello Astie,
Please make sure your datanode is up. I think you have not included
"hadoop.tmp.dir", "dfs.name.dir" and "dfs.data.dir" properties. The value
of these props default to the /tmp dir, which gets emptied on each restart.
As a result you loose all your data and meta information.
Regards,
Mohammad Tariq

Astie,
Since you've overriden these, do:
$ rm -rf /home/astie/hdfs/data
And then re-run your start-all command. After this works, please never
re-issue a "namenode -format" unless you really want to wipe
everything away and start over.

Re: Can not generate a result

Astie,
Since you've overriden these, do:
$ rm -rf /home/astie/hdfs/data
And then re-run your start-all command. After this works, please never
re-issue a "namenode -format" unless you really want to wipe
everything away and start over.

Hi Astie,
> Live Nodes:0
That the live nodes = 0 is the real issue here.
If you're running off of default configs (i.e. haven't overriden
hadoop.tmp.dir, dfs.name.dir, nor dfs.data.dir), do this:
$ rm -rf /tmp/hadoop-$(whoami)/dfs/data
And then:
$ $HADOOP_HOME/bin/start-all.sh
And you should see:
> Live Nodes : 1
And then your HDFS should work alright.

That the live nodes = 0 is the real issue here.
If you're running off of default configs (i.e. haven't overriden
hadoop.tmp.dir, dfs.name.dir, nor dfs.data.dir), do this:
$ rm -rf /tmp/hadoop-$(whoami)/dfs/data
And then:
$ $HADOOP_HOME/bin/start-all.sh
And you should see:

If you're running off of default configs (i.e. haven't overriden
hadoop.tmp.dir, dfs.name.dir, nor dfs.data.dir), do this:
$ rm -rf /tmp/hadoop-$(whoami)/dfs/data

Hi Astie,
You can look at http://wiki.apache.org/hadoop/CouldOnlyBeReplicatedTo
to find a solution on this one. Speaking w.r.t. first-timers, this
frequently happens when you format the NameNode but forget to wipe the
DataNode block directories at the same time.

Re: Can not generate a result
Posted by Mohammad Tariq <do...@gmail.com>.
Hello Astie,
Please make sure your datanode is up. I think you have not included
"hadoop.tmp.dir", "dfs.name.dir" and "dfs.data.dir" properties. The value
of these props default to the /tmp dir, which gets emptied on each restart.
As a result you loose all your data and meta information.
Regards,
Mohammad Tariq

Hello Astie,
Please make sure your datanode is up. I think you have not included
"hadoop.tmp.dir", "dfs.name.dir" and "dfs.data.dir" properties. The value
of these props default to the /tmp dir, which gets emptied on each restart.
As a result you loose all your data and meta information.

Hi Astie,
You can look at http://wiki.apache.org/hadoop/CouldOnlyBeReplicatedTo
to find a solution on this one. Speaking w.r.t. first-timers, this
frequently happens when you format the NameNode but forget to wipe the
DataNode block directories at the same time.
