fsck command can display usage if user passes any other arguments with '-' ( other than -move, -delete, -files , -openforwrite, -blocks , -locations, -racks). --------------------------------------------------------------------------------------------------------------------------------------------------------------
Key: HDFS-1727 URL: https://issues.apache.org/jira/browse/HDFS-1727 Project: Hadoop HDFS Issue Type: Bug Reporter: Uma Maheswara Rao G Priority: Minor In fsck command if user passes the arguments like ./hadoop fsck -test -files -blocks -racks In this case it will take / and will display whole DFS information regarding to files,blocks,racks. But here, we are hiding the user mistake. Instead of this, we can display the usage if user passes any invalid argument like above. -- This message is automatically generated by JIRA.
