-/**
- * {@code IGFS} Hadoop 2.x file system driver over file system API. To use
- * {@code IGFS} as Hadoop file system, you should configure this class
- * in Hadoop's {@code core-site.xml} as follows:
- * <pre name="code" class="xml">
- * <property>
- * <name>fs.default.name</name>
- * <value>igfs://ipc</value>
- * </property>
- *
- * <property>
- * <name>fs.igfs.impl</name>
- * <value>org.apache.ignite.igfs.hadoop.v2.IgfsHadoopFileSystem</value>
- * </property>
- * </pre>
- * You should also add Ignite JAR and all libraries to Hadoop classpath. To
- * do this, add following lines to {@code conf/hadoop-env.sh} script in Hadoop
- * distribution:
- * <pre name="code" class="bash">
- * export IGNITE_HOME=/path/to/Ignite/distribution
- * export HADOOP_CLASSPATH=$IGNITE_HOME/ignite*.jar
- *
- * for f in $IGNITE_HOME/libs/*.jar; do
- * export HADOOP_CLASSPATH=$HADOOP_CLASSPATH:$f;
- * done
- * </pre>
- * <h1 class="header">Data vs Clients Nodes</h1>
- * Hadoop needs to use its FileSystem remotely from client nodes as well as directly on
- * data nodes. Client nodes are responsible for basic file system operations as well as
- * accessing data nodes remotely. Usually, client nodes are started together
- * with {@code job-submitter} or {@code job-scheduler} processes, while data nodes are usually
- * started together with Hadoop {@code task-tracker} processes.
- * <p>
- * For sample client and data node configuration refer to {@code config/hadoop/default-config-client.xml}
- * and {@code config/hadoop/default-config.xml} configuration files in Ignite installation.
