Shell¶

Crail provides an implementation of the HDFS API thus allows interaction using the HDFS shell. For the HDFS adapter to work properly the core-site.xml needs to be configured properly.

$CRAIL_HOME/bin/crail fs

Not all shell commands are support but the following operations have been tested to work:

$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>
