St.Ack,
Thanks a lot When I will be back in office I need to reinstall everything.
In this case do I need to reinstall hadoop too. Because my datanode has
hbase directory in its listings.
When I say I will move means I will move with my dev laptop. Are you saying
hbase is mean to work on static location(i.e. fixed machine name and IP)?

Re: Could not resolve the DNS name of unknown
Posted by Stack <st...@duboce.net>.
That the servername makes no sense in a particular context has been
fixed in newer versions of hbase.
Is the data in your dev laptop critical? If not just throw it away
when you move or update.
HBase has not been optimized to run on fellows' laptops.

Re: Could not resolve the DNS name of unknown
Posted by Jignesh Patel <ji...@gmail.com>.
Statck,
I am at home now in my home network I see one change now the machine name
is unknowne4ce8f3898fc.
I will fix this by taking help from Mac people.
But tomorrow I might go from x to y place and machine name may be different
there.So again Hbase will stop working.
But as per the previous post even after fixing the weird machine name issue
hbase is not going to forget this name. So what action I need to take so
that hbase will take up the correct machine name.

Try making it resolve temporarily by adding it to your /etc/hosts.

Re: Could not resolve the DNS name of unknown
Posted by Jignesh Patel <ji...@gmail.com>.
When I start the hbase first time I always see following error.
ERROR: java.lang.reflect.UndeclaredThrowableException: Call to
192.168.1.120/192.168.1.120:49188 failed on local exception:
java.io.EOFException
but my log file shows
2011-10-21 15:45:21,772 ERROR org.apache.hadoop.hbase.HServerAddress: Could
not resolve the DNS name of unknowne4ce8f3898fc
2011-10-21 15:45:21,773 FATAL org.apache.hadoop.hbase.master.HMaster:
Unhandled exception. Starting shutdown.
java.lang.IllegalArgumentException: hostname can't be null
How to debug this. Even by searching in the old email it says there was a
bug in 0.90 which is fixed. I am not able to get anything more.

Re: Could not resolve the DNS name of unknown
Posted by Jignesh Patel <ji...@gmail.com>.
I have clean up the zookeeper and it seems my computer name is also changed
today as setting of dynamic ip.
Jignesh-MacBookPro:hadoop hadoop-user$ hostname
Jignesh-MacBookPro.local
But I still have old error
Could not resolve the DNS name of *unknowne4ce8f3898fc*
Why would HServerAddress get old name, instead of taking the latest one.
According to the following article, it advise us to refrain from adding
hardcoded name as hadoop is efficient to pickup the appropriate DNS name.

Re: Could not resolve the DNS name of unknown
Posted by Shrijeet Paliwal <sh...@rocketfuel.com>.
Look for a DNS /etc/hosts related suggestion mentioned here :
http://search-hadoop.com/m/N45fnRFrG12
also here http://ria101.wordpress.com/2010/01/28/setup-hbase-in-pseudo-distributed-mode-and-connect-java-client/
Also clean up data from zookeeper if needed and do a restart of
services , zookkper directory is here usually :
${hbase.tmp.dir}/zookeeper
PS: This issues has been reported bunch of times. Look deeper in
mailing archives for changes required in /etc/hosts to get standalone
hbase running.

I have tried to take help from Mac group and their respond.
"An app you wrote, or somebody else's app?
I'm not sure exactly how you want us to help, unknowne4ce8f3898fc is indeed
an invalid hostname."
According to them it seems this is a app problem, but I haven' changed
anything and my zookeeper recognizes the IP.

As Stack pointed out in other thread , you can find mac OS communities more
