File Extensions of Compressed Files
Lists extensions of compressed files.
By default, MapR does not compress files whose filename extensions indicate they are already compressed. The default list of filename extensions is as follows:
- bz2
- gz
- lzo
- snappy
- tgz
- tbz2
- zip
- z
- Z
- mp3
- jpg
- jpeg
- mpg
- mpeg
- avi
- gif
- png
The list of filename extensions not to compress is stored as comma-separated values in the
mapr.fs.nocompression
configuration parameter and can be modified with the
config
save
command. For example, you can add parquet
to the
default list:
maprcli config save -values '{"mapr.fs.nocompression":"bz2,gz,lzo,snappy,tgz,tbz2,zip,z,Z,mp3, \
jpg,jpeg,mpg,mpeg,avi,gif,png,parquet"}'
The list can be viewed with the config load
command. Example:
maprcli config load -keys mapr.fs.nocompression
