In order to interact with HDFS, a command line interface named _____ is provided.
HDFS Shell
DFS Shell
K Shell
FS Shell
Correct Answer :
D. FS Shell
It is possible to view the contents of a directory indicated in the path provided by the user by using the Hadoop FS shell command ls. All FS shell commands accept URIs for path names as inputs. Scheme:/authority/path is the URI format used in this example. In the case of HDFS, the scheme is hdfs, and in the case of the Local File System, the scheme is file. The scheme as well as the authority is entirely optional. Otherwise, the default scheme supplied in the configuration will be utilized if it is not explicitly specified.
