Hi Expert,
Below are my steps and is it a hadoop bug or did I miss any thing? Thanks!
Step:
[A] Upgrade
1. Install Hadoop 2.2.0 cluster
2. Stop Hadoop services
3. Replace 2.2.0 binaries with 2.4.1 binaries
4. Start datanodes: $HADOOP_HOME/sbin/hadoop-daemon.sh start datanode
5. Start namenode
Thanks,
I made the changes and everything works fine!! Many thanks!!
Now I am having problems converting BSONWritable to BSONObject and vice versa.
Is there an automatic way to make it?
Or should I write myself a parse?
And regarding the tests on windows, any experience?
Thanks again!!
Best
Dear Yu, this is a snippet of log , thank you for diagnosis!
it seems the upstream socket cracks. but i can't find valuable clue from other
datanode's log!

You have to upgrade both name node and data node.
Better issue start-dfs.sh -upgrade.
Check whether current and previous directories are present in both
dfs.namenode.name.dir and dfs.datanode.data.dir directory.

Please check if /etc/hadoop/conf/ exists.
If it exists then export enviroment variable HADOOP_CONF_DIR set to this
path.

Thanks for your comment!
I can upgrade from 2.2.0 to 2.4.1 using command 'start-dfs.sh -upgrade',
however failed to rollback from 2.4.1 to 2.2.0 using command 'start-dfs.sh
-rollback': the namenode always stays on safe mode(awaiting reported blocks
(0/315)).
Why?

In the installation process /etc/hadoop/conf.pseudo/ directory was made
which contains all the hdfs files: core-site.xml, hdfs-site.xml,
mapred-site.xml,
yarn-site.xml

If it exists
Please check if /etc/hadoop/conf/ is present and is a symbolic link to some
other directory that doesn't exists.
Ideally this should be take care by installer, are you sure that you didn't
have an already existing hadoop setup on that machine?

/etc/hadoop/conf/ is not present. Earlier i tried to install hadoop by
apache hadoop and cdh4 installation too, but i had uninstalled both, still
unable to figure out the error

What is the o/p of command
hdfs dfsadmin -upgradeProgress status
If it says upgrade is complete then you can do some sanity check by hdfs fsck.
Stop the servers by stop-dfs.sh and then rollback by command
start-dfs.sh -rollback

A quick fix is to run this command
ln -s /etc/hadoop/conf.pseudo /etc/hadoop/conf

You will have to convert BSONWritable to BSONObject yourself. You can
abstract this parsing in a separate class/object model and reuse it but as
far as I understand, objects being serialized or deserialized have to be
Writable (conforming to the interface that Hadoop defines and Comparable if
Correct. This is for client communication to the cluster.
I’m talking about “yarn.resourcemanager.hostname” which is still used to
construct the composite UI, it seems.

Follow-up: problem seem to be solved.
The issue is purely a JNI issue and actually doesn't have anything to do with
security per se. Calling vm-AttachCurrentThread() sets the context class
loader to the bootstrap loader, which is insufficient for ServiceLoader to
function properly. Any C++
