Voldemort Admin tool
The Voldemort admin tool allows you to run administrative commands such as streaming and migrating partitions , changing metadata e.g., adding new machines to the cluster or adding new stores.
1) Get all metadata from all nodes
./bin/voldemort-admin-tool.sh --get-metadata --url [url]2) Get metadata from all nodes
./bin/voldemort-admin-tool.sh --get-metadata [cluster.xml, stores.xml, server.state, node.id, rebalancing.steal.info.key] --url [url]3) Get metadata from a particular node
./bin/voldemort-admin-tool.sh --get-metadata [cluster.xml, stores.xml, server.state, node.id, rebalancing.steal.info.key] --url [url] --node [node-id]4) Get metadata from a particular node and store to a directory
./bin/voldemort-admin-tool.sh --get-metadata [cluster.xml, stores.xml, server.state, node.id, rebalancing.steal.info.key] --url [url] --node [node-id] --outdir [directory]5) Set metadata on all nodes
./bin/voldemort-admin-tool.sh --set-metadata [cluster.xml, server.state, stores.xml, rebalancing.steal.info.key] --set-metadata-value [metadata-value] --url [url]6) Set metadata for a particular node
./bin/voldemort-admin-tool.sh --set-metadata [cluster.xml, server.state, stores.xml, rebalancing.steal.info.key] --set-metadata-value [metadata-value] --url [url] --node [node-id]7) Check if metadata is same on all nodes
./bin/voldemort-admin-tool.sh --check-metadata [cluster.xml, server.state, stores.xml] --url [url]8) Clear rebalancing metadata [server.state, rebalancing.steal.info.key] on all node
./bin/voldemort-admin-tool.sh --clear-rebalancing-metadata --url [url]9) Clear rebalancing metadata [server.state, rebalancing.steal.info.key] on a particular node
./bin/voldemort-admin-tool.sh --clear-rebalancing-metadata --url [url] --node [node-id]1) Add store(s) on all nodes
./bin/voldemort-admin-tool.sh --add-stores [xml file with store(s) to add] --url [url]2) Add store(s) on a single node
./bin/voldemort-admin-tool.sh --add-stores [xml file with store(s) to add] --url [url] --node [node-id]3) Delete store on all nodes
./bin/voldemort-admin-tool.sh --delete-store [store-name] --url [url]4) Delete store on a single node
./bin/voldemort-admin-tool.sh --delete-store [store-name] --url [url] --node [node-id]5) Delete the contents of the store on all nodes
./bin/voldemort-admin-tool.sh --truncate [store-name] --url [url]6) Delete the contents of the store on a single node
./bin/voldemort-admin-tool.sh --truncate [store-name] --url [url] --node [node-id]7) Delete the contents of some partitions on a single node
./bin/voldemort-admin-tool.sh --delete-partitions [comma-separated list of partitions] --url [url] --node [node-id]8) Delete the contents of some partitions ( of some stores ) on a single node
./bin/voldemort-admin-tool.sh --delete-partitions [comma-separated list of partitions] --url [url] --node [node-id] --stores [comma-separated list of store names]1) Fetch keys from a set of partitions [ all stores ] on a node ( binary dump )
./bin/voldemort-admin-tool.sh --fetch-keys [comma-separated list of partitions with no space] --url [url] --node [node-id]2) Fetch keys from a set of partitions [ all stores ] on a node ( ascii enabled )
./bin/voldemort-admin-tool.sh --fetch-keys [comma-separated list of partitions with no space] --url [url] --node [node-id] --ascii3) Fetch entries from a set of partitions [ all stores ] on a node ( binary dump )
./bin/voldemort-admin-tool.sh --fetch-entries [comma-separated list of partitions with no space] --url [url] --node [node-id]4) Fetch entries from a set of partitions [ all stores ] on a node ( ascii enabled )
./bin/voldemort-admin-tool.sh --fetch-entries [comma-separated list of partitions with no space] --url [url] --node [node-id] --ascii5) Fetch entries from a set of partitions [ all stores ] on a node ( ascii enabled ) and output to a folder
./bin/voldemort-admin-tool.sh --fetch-entries [comma-separated list of partitions with no space] --url [url] --node [node-id] --ascii --outdir [directory]6) Fetch entries from a set of partitions and some stores on a node ( ascii enabled )
./bin/voldemort-admin-tool.sh --fetch-entries [comma-separated list of partitions with no space] --url [url] --node [node-id] --ascii --stores [comma-separated list of store names] 7) Fetch all keys on a particular node
./bin/voldemort-admin-tool.sh --fetch-keys --url [url] --node [node-id]8) Fetch all entries on a particular node
./bin/voldemort-admin-tool.sh --fetch-entries --url [url] --node [node-id]9) Update entries for a set of stores using the output from a binary dump fetch entries
./bin/voldemort-admin-tool.sh --update-entries [folder path from output of --fetch-entries --outdir] --url [url] --node [node-id] --stores [comma-separated list of store names]1) Retrieve metadata information of read-only data for a particular node and all stores
./bin/voldemort-admin-tool.sh --ro-metadata [current | max | storage-format] --url [url] --node [node-id]2) Retrieve metadata information of read-only data for all nodes and a set of store
