HPE Ezmeral Data Fabric Database Binary FormatResult

Parses a sequence file generated by the DiffTables utility or the DiffTablesWithCrc utility and converts the results into a format that makes the results easier to understand.

Required Permissions

The user that runs the FormatResult utility must have the readAce and writeAce permissions on the volumes where the input and output paths are located.

For information about how to set permissions on volumes, see Setting Whole Volume ACEs.

NOTE
The mapr user is not treated as a superuser. HPE Ezmeral Data Fabric Database does not allow the mapr user to run this utility unless that user is given the relevant permission or permissions with access-control expressions.

Syntax

hbase com.mapr.fs.hbase.tools.mapreduce.FormatResult 
-input <input file path>
-output <output file path> 
[-mapreduce <true|false> (default: false)]

Parameters

Parameters Description
input

The path to a file or directory of files that contains the output of either the DiffTables utility or the DiffTablesWithCrc utility.
output The path to a file or a directory for the output. If the file or directory already exists, the utility fails. When a single sequence file is provided as input, the utility generates a single output file. When a directory of sequence files is provided as input, the utility generates a directory with output files.
mapreduce

A Boolean value that specifies whether or not to use a MapReduce program to perform the FormatResult operation. The default is not to use a MapReduce program (false).

Example

Formats a sequence file: 
[user@hostname ~]$ hbase com.mapr.fs.hbase.tools.mapreduce.FormatResult -input /dif1/tf4/opsForDst/opsForDst-m-00001 -output /dif1/tf4/opsForDst_single/nomr -mapreduce false
