             Summary: Wrong staging permissions while running MR job under hadoop accelerator
                 Key: IGNITE-218
                 URL: https://issues.apache.org/jira/browse/IGNITE-218
             Project: Ignite
          Issue Type: Bug
          Components: hadoop
    Affects Versions: sprint-1
            Reporter: Konstantin Boudnik


I am trying to run an MR example on gridgain-hadoop setup in Bigtop. The ggfs is configured
to be backed by HDFS with
{code}
        <property name="secondaryFileSystem">
          <bean class="org.gridgain.grid.kernal.ggfs.hadoop.GridGgfsHadoopFileSystemWrapper">
            <constructor-arg value="hdfs://vmhost05-hbase1.bdva.wandisco.com:8020"/>
            <constructor-arg value="/etc/hadoop/conf/hdfs-site.xml"/>
          </bean>
        </property>
{code}
set for {{ggfsConfiguration}}
While all usual filesystem operations work properly, running an MR job produces the following
exception in the beginning of the run
{noformat}
HADOOP_CONF_DIR=/etc/hadoop/gridgain.client.conf hadoop jar /usr/lib/hadoop-mapreduce/hadoop-mapreduce-examples.jar

However the permissions seem to be correct.
