Works like -get, but deletes the HDFS copy on success. Creates any parent directories in path that are missing e. The actual replication factor will move toward the target over time -touchz path Creates a file at path containing the current time as a timestamp.
Fails if a file already exists at path, unless the file is already size 0. Changes the file permissions associated with one or more objects identified by path Performs changes recursively with -R.
Assumes a if no scope is specified and does not apply a umask. Sets owner recursively if -R is specified. Sets the owning group for files or directories identified by path Sets group recursively if -R is specified.
The dfsadmin module manipulates or queries the file system as a whole. The operation of the commands in this module is described in this section. This returns basic information about the overall health of the HDFS cluster, as well as some per-server metrics.
The metasave command will enumerate lists of blocks which are under-replicated, in the process of being replicated, and scheduled for deletion. The help for this command states that it "saves NameNode's primary data structures," but this is a misnomer; the NameNode's state cannot be restored from this information.
Safemode is an HDFS state in which the file system is mounted read-only; no replication is performed, nor can files be created or deleted. This is automatically entered as the NameNode starts, to allow all DataNodes time to check in with the NameNode and announce which blocks they hold, before the NameNode determines which blocks are under-replicated, etc.
The NameNode waits until a specific percentage of the blocks are present and accounted-for; this is controlled in the configuration by the dfs. After this threshold is met, safemode is automatically exited, and HDFS allows normal operations.
See the section on decommissioning later in this document for an explanation of the use of the -refreshNodes dfsadmin command. When you first start the new version of Hadoop on the cluster, you need to tell Hadoop to change the HDFS version or else it will not mountusing the command: It will then begin upgrading the HDFS version.
If the upgrade is blocked and you would like to force it to continue, use the command: To back out the changes, stop the cluster, re-install the older version of Hadoop, and then use the command: It will restore the previous HDFS state.
Only one such archival copy can be kept at a time. The rollback command cannot be issued after this point. This must be performed before a second Hadoop upgrade is allowed.
