21.5. FileSystem Command-Line Tools

The GeoMesa FileSystem distribution includes a set of command-line tools for feature management, ingest, export and debugging.

To install the tools, see Setting up the FileSystem Command Line Tools.

Once installed, the tools should be available through the command geomesa-fs:

$ geomesa-fs
INFO  Usage: geomesa-fs [command] [command options]
  Commands:
    ...

Commands that are common to multiple back ends are described in Command-Line Tools. The commands here are FileSystem-specific.

21.5.1. General Arguments

Most commands require the --path argument, to specify the root storage path. Configuration properties can be passed in using --config or --config-file, which can be used to specify e.g. s3-related properties.

The --auths argument corresponds to the data store parameter geomesa.security.auths. See Data Security for more information.

21.5.2. Commands

21.5.2.1. compact

Compact one or more filesystem partitions. This will merge multiple files into fewer, larger files, which may provide better query performance.

Argument	Description
-p, --path *	The filesystem root path used to store data
-f, --feature-name *	The name of the schema
--partitions	Partitions to compact (omit to compact all partitions)
--target-file-size	Target size for data files (e.g. 500MB or 1GB)
--mode	One of local or distributed (to use map/reduce)
--temp-path	Path to a temp directory used for working files

The --temp-path argument may be useful when working with s3 data, as s3 is slow for incremental writes.

21.5.2.2. generate-partition-filters

Calculate filters that exactly match partitions. This can be used to facilitate exports from another system directly into the appropriate partition directory.

Argument	Description
-p, --path *	The filesystem root path used to store data
-f, --feature-name *	The name of the schema
-q, --cql	CQL predicate to determine the partitions to operate on
--partitions	Partitions to operate on
--no-header	Suppress the column headers in the output

At least one of --cql or --partitions must be specified, to select the partitions being operated on.

The results will be output in tab-delimited text, containing the partition name and the associated filter.

21.5.2.3. get-files

Displays the files for one or more filesystem partitions.

Argument	Description
-p, --path *	The filesystem root path used to store data
-f, --feature-name *	The name of the schema
--partition	Partitions to list (omit to list all partitions)
-q, --cql	CQL predicate to determine the partitions to operate on

21.5.2.4. get-partitions

Displays the partitions for a given filesystem store.

Argument	Description
-p, --path *	The filesystem root path used to store data
-f, --feature-name *	The name of the schema

21.5.2.5. ingest

For an overview of ingestion options, see ingest.

This command ingests files into a GeoMesa FS Datastore. Note that a “datastore” is simply a path in the filesystem. All data and metadata will be stored in the filesystem under the hierarchy of the root path.

Argument	Description
-p, --path *	The filesystem root path used to store data
--partition-scheme	Partition schemes
--num-reducers	Number of reducers to use (required for distributed ingest)
--target-file-size	Target size for data files (e.g. 500MB or 1GB)
--temp-path	Path to a temp directory used for working files
--storage-opt	Additional storage options to set as SimpleFeatureType user data, in the form key=value

If the schema does not already exist, then --partition-scheme is required, otherwise it may be omitted.

The --partition-scheme argument should be the well-known name of a provided partition scheme. See Partition Schemes for more information.

The --num-reducers should generally be set to half the number of partitions.

The --temp-path argument may be useful when working with s3 data, as s3 is slow to write to.

21.5.2.6. manage-metadata

This command will compact, add and delete metadata entries in a file system storage instance. It has four sub-commands:

• register - create a new metadata entry for an existing data file

• unregister - remove a metadata entry for an existing data file

• migrate - migrate metadata from one type to another

• check-consistency - check consistency between the metadata and data files

To invoke the command, use the command name followed by the sub-command, then any arguments. For example:

$ geomesa manage-metadata compact -p /tmp/geomesa ...

Argument	Description
-p, --path *	The filesystem root path used to store data
-f, --feature-name *	The name of the schema

21.5.2.6.1. register

The register sub-command will add metadata associated with a particular file. When new data files are created through some external bulk process, then they must be registered using this command before they are queryable. Note that generally files must already be in the same filesystem in order to be registered.

Argument	Description
<file> *	The path of the file(s) to register
--delete	Delete files after copying them into the storage root path

21.5.2.6.2. unregister

The unregister sub-command will the delete metadata associated with a particular file.

Argument	Description
<file> *	The path of the file to unregister, relative to the storage root path

21.5.2.6.3. migrate

The migrate sub-command will move the metadata storage from one type (file or jdbc) to another.

Argument	Description
--new-metadata-type *	Metadata type to migrate to
--new-metadata-config	Metadata configuration properties for the type to migrate to, in the form k=v
--new-metadata-config-file	Name of a metadata configuration file for the type to migrate to, in Java properties format

21.5.2.6.4. check-consistency

The check-consistency sub-command will check the metadata against the data files. It will find data files that are not referenced in the metadata, and metadata entries that do not correspond to data files.

Argument	Description
--partition	The name of partitions to check, or none for all partitions
--threads, -t	Number of threads to use when listing data files
