| `-evictWriters` \<datanode\_host:ipc\_port\> | Make the datanode evict all clients that are writing a block. This is useful if decommissioning is hung due to slow writers. |
| `-getDatanodeInfo` \<datanode\_host:ipc\_port\> | Get the information about the given datanode. See [Rolling Upgrade document](./HdfsRollingUpgrade.html#dfsadmin_-getDatanodeInfo) for the detail. |
| `-metasave` filename | Save Namenode's primary data structures to *filename* in the directory specified by hadoop.log.dir property. *filename* is overwritten if it exists. *filename* will contain one line for each of the following<br/>1. Datanodes heart beating with Namenode<br/>2. Blocks waiting to be replicated<br/>3. Blocks currently being replicated<br/>4. Blocks waiting to be deleted |
| `-triggerBlockReport` `[-incremental]` \<datanode\_host:ipc\_port\> `[-namenode]` \<namenode\_host:ipc\_port\> | Trigger a block report for the given datanode. If 'incremental' is specified, it will be otherwise, it will be a full block report. If '-namenode \<host\>:\<port\>' is given, it only sends block report to a specified namenode. |
| `-triggerBlockReport` `[-incremental]` \<datanode\_host:ipc\_port\> `[-namenode <namenode_host:ipc_port>]` | Trigger a block report for the given datanode. If 'incremental' is specified, it will be otherwise, it will be a full block report. If '-namenode \<namenode\_host:ipc\_port\>' is given, it only sends block report to a specified namenode. |
| `-listOpenFiles` `[-blockingDecommission]` `[-path <path>]` | List all open files currently managed by the NameNode along with client name and client machine accessing them. Open files list will be filtered by given type and path. Add -blockingDecommission option if you only want to list open files that are blocking the DataNode decommissioning. |
| `-help` [cmd] | Displays help for the given command or all commands if none is specified. |
