Re: NoServerforRegionexception
Hi,
I am having the Hadoop-CDH3 pseudo distributed environment. I am running the
Map Reduce program to do the Bulk load of data into the Hbase-0.89, I am
getting the following exception.
org.apache.hadoop.hbase.client.NoServerForRegionException: Timed out trying
to locate root region
> � � � �at
org.apache.hadoop.hbase.client.HConnectionManager$TableServers.locateRootRegion(HConnectionManager.java:983)
> � � � �at
org.apache.hadoop.hbase.client.HConnectionManager$TableServers.locateRegion(HConnectionManager.java:625)
But the same job running in the another Pseudo distributed Machine. I
followed the following link to resolve the problem. But its not clear for
me.

Please help to get rid of this Error!
Thank you

Guys,
I got out of this error! This seems only permission issues to the
$HBASE_HOME/conf/hbase-site.xml. Just copying the hbase-site.xml into the
$HADOOP_HOME/conf/ directory and restarting the cluster resolves the error.

Stack, Thanks. I can able to understand. I am just developing the model.
Could you please be exact? About the error. I am very new to hbase. Many of
them by your clear answer.
Thank you Stack

The below error is telling you that -ROOT- is not assigned. Grep logs
to try figure what happened to it. Try restart to see if it brings it
back.
You are aware that pseudo-distributed mode is for dev and exploration
only. It'll likely not do too well if you are trying to load a bunch
of data into it.
