Hello all,
I am using HBase within a Map/Reduce job, and when I run the job, it
exits with the following error:
09/07/06 18:34:42 INFO mapred.JobClient: Task Id :
attempt_200907061758_0004_m_000000_0, Status : FAILED

I am running Hadoop 0.19.1 with HBase 0.19.3. I have a cluster of 5
nodes, with one node (named 'elroy' == 10.1.0.200) serving as the Hadoop
namenode and jobtracker and the HBase Master.
My hbase-site.xml:
<configuration>
<property>
<name>hbase.rootdir</name>
<value>hdfs://elroy/hbase</value>
</property>
<property>
<name>hbase.master</name>
<value>elroy:6000</value>
</property>
</configuration>
My regionservers:
10.1.0.200
10.1.0.201
10.1.0.202
10.1.0.203
10.1.0.204
It seems that when the Map/Reduce job attempts to contact the HBase
database, it tries to do so on localhost:6000 instead of elroy:6000...
Since I have hbase.master set in hbase-site.xml, I am not sure why it is
doing this.
Any suggestions?
Thanks,
John Noecker Jr.
