Re: Issue against Hadoop-2.0.4-alpha
Hi Jarek,

Yes, the hdfs-site.xml file is in ${HADOOP_HOME}/etc/hadoop. I also added
hadoop related jars into CLASSPATH:
'/home/hadoop-2.0.3-alpha/share/hadoop/common/hadoop-common-2.0.3-alpha.jar:/home/hadoop-2.0.3-alpha/share/hadoop/mapreduce/*.jar:/home/hadoop-2.0.3-alpha/share/hadoop/yarn/*.jar:/home/hadoop-2.0.3-alpha/share/hadoop/hdfs/hadoop-hdfs-2.0.3-alpha.jar:...',
but Sqoop import tool still failed due to same exception.

Below is my core-site.xml:
<configuration>
  <property>
    <name>fs.default.name</name>
    <value>hdfs://namenode_hostname:9010/</value>
  </property>

  <property>
     <name>hadoop.tmp.dir</name>
     <value>/home/temp/hadoop/core_temp</value>
  </property>

</configuration>
Thanks!
