| Shell |
| ===== |
| |
| Crail provides an implementation of the HDFS API thus allows interaction using the HDFS shell. |
| For the HDFS adapter to work properly the :ref:`core-site.xml` needs to be configured |
| properly. |
| |
| .. code-block:: bash |
| |
| $CRAIL_HOME/bin/crail fs |
| |
| Not all shell commands are support but the following operations have been tested to work: |
| |
| .. code-block:: bash |
| |
| $CRAIL_HOME/bin/crail fs -ls <crail_path> |
| $CRAIL_HOME/bin/crail fs -mkdir <crail_path> |
| $CRAIL_HOME/bin/crail fs -copyFromLocal <local_path> <crail_path> |
| $CRAIL_HOME/bin/crail fs -copyToLocal <crail_path> <local_path> |
| $CRAIL_HOME/bin/crail fs -cat <crail_path> |
| |
