where can i get the old hadoop documentation (e.g. cluster setup, xml
configuration params) for hadoop v0.22.0 and below? i downloaded the source
and binary files but could not find the documentations as a part of the
archive file.
on the home page at http://hadoop.apache.org/, i only see
I think your best bet might be to check out a particular release tag for 0.22
release and checking the docs out there. Perhaps you might want to run 'ant
docs' of whatever the target used to be back then.

hi,
How can i store images in hadoop/hive and perform some processing on it?
Is there any inbuilt library available to do so?
how hadoop stores images in HDFS

Please run it in the same style. The binary 'java' accepts a -cp param too:
java -cp $($HADOOP_HOME/bin/hadoop classpath):. PutMerge

Thanks a lot! I could compile with the added classpath:
$javac -cp $($HADOOP_HOME/bin/hadoop
This appears to be an JDBC end issue (not Sqoop's issue). You likely
have a mix of different Oracle JDBC (non-DMS and DMS ones?) jars under
$SQOOP_HOME/lib or other locations. This is causing a class loading
conflict.

Hi,
I can probably help you out with that. I don¹t want to sound patronising
though. What is your IDE and have you included the hadoop libraries in
your jar ?

Hi,
Could you try putting this in .bash_profile

Hi Ravindra,
Thanks for replying, it’s much appreciated.
That’s always been the case with my setup:
export HADOOP_PREFIX=/scratch/extra/cm469/hadoop-2.4.1
export HADOOP_CONF_DIR=$HADOOP_PREFIX/etc/hadoop
I think my issue is that I have not set yarn-env.sh up correctly. TBH I

Hello,
I have hadoop cluster setup of one namenode and two datanodes.
And i continuously write/read/delete through hdfs on namenode through
hadoop client.
Then i kill one of the datanode, still one is working but writing on
datanode is getting failed for all write requests.
I want to
Can you make sure you still have enough HDFS space once you kill this DN? If
not, HDFS will automatically enter safemode if it detects there's no hdfs space
available. The error message on the logs should have some hints on this.
Cheers.

Yes, there is lot of space available at that instant.
I am not sure but i have read somewhere that we must have datanodes live
= replication factor given at namenode at any point of time. If live
datanodes get less than replication factor then this write/read failure
occurs.
In my case i

I compileted with the command:

@vikas i have initially set 2 but after that i have make one DN down. So
you are saying from initial i have to make replication factor as 1 even
i have DN 2 active initially. If so then what is the reason?
On 07/28/2014 10:02 PM, Vikas Srivastava wrote:
What replication have you set for
The reason being that when you write something in HDFS, it guarantees that
it will be written to the specified number of replicas. So if your
replication factor is 2 and one of your node (out of 2) is down, then it
cannot guarantee the 'write'.
The way to handle this to have a cluster of more
If you have 2 an live initially and rep set to 2 which is perfectly fine
but you killed one dn... There is no place to put another replica of new
files as well as old files... Which causing issue in writing blocks.

You need to add each disk inside dfs.name.data.dir parameter.
