Note

These reports are currently available only for CDH, CDP, and HDP and require HDFS administrator privileges. If you can't grant HDFS administrator privileges to the user unravel, refer to configuring FSimage.Configuring FSImage

This report is the same as the Small Files report except they are automatically generated using the File Reports properties. By default, these reports are updated every 24 hours and are archived.

The default size for the files are:

  • Large is any file with more than 100 GB size,

  • Medium is any file with 5 GB - 10 GB size.

  • Tiny is any file with less than 100 KB size.

  • Empty is a file with 0 bytes.

Configuring the Files report

  1. Stop Unravel

    <Unravel installation directory>/unravel/manager stop

  2. Set the File report properties using any of the following options.

    • Option 1

      1. Create a file containing the properties of Files report that you want to configure and their corresponding values. For example:

        unravel.python.reporting.files.huge.files.min.parent.dir.depth=2
unravel.python.reporting.files.huge.files.max.parent.dir.depth=5
unravel.python.reporting.files.huge.files.min.files=3
unravel.python.reporting.files.huge.files.threshold.size=1024* 1024* 1024
unravel.python.reporting.files.huge.files.top.n.dirs=300
unravel.python.reporting.files.huge.files.use.avg.file.size.flag=true

      2. From the installation directory, where Unravel binaries are installed, run the following command and provide the path to the properties file.

        <Unravel installation directory>/unravel/manager config properties import <path to the properties file>

##For example:
/opt/unravel-install/unravel/manager config properties import /opt/properties.txt

    • Option 2

      From the installation directory, where Unravel binaries are installed, set the properties as follows:

      <Unravel installation directory>/unravel/manager config properties set <property> <value>

##For example:
unravel.python.reporting.files.huge.files.min.parent.dir.depth 2
unravel.python.reporting.files.huge.files.max.parent.dir.depth 5
unravel.python.reporting.files.huge.files.min.files 3
unravel.python.reporting.files.huge.files.threshold.size 1024* 1024* 1024
unravel.python.reporting.files.huge.files.top.n.dirs 300
unravel.python.reporting.files.huge.files.use.avg.file.size.flag true
