The following command would check the configuration for errors:

With the compaction configuration set, configure table specific properties.

Generate some data and files in order to test the strategy:

$ accumulo shell -u <username> -p <password> -e "flush -t examples.test1"
$ accumulo shell --user root --password secret -e "flush -t examples.test1"

$ ./bin/runex client.SequentialBatchWriter -t examples.test1 --start 0 --num 2000 --size 50

$ accumulo shell --user root --password secret -e "compact -t examples.test1 -w"

View the `tserver` log in <accumulo_home>/logs for the compaction and find the name of the `rfile` that was
compacted for your table. Print info about this file using the `rfile-info` tool. Replace the TableID with
the TableID from above. Note, your filenames will differ from the ones within this example.

accumulo rfile-info hdfs:///accumulo/tables/2/default_tablet/A000000a.rf
$ accumulo file rfile-info hdfs:///accumulo/tables/2/default_tablet/A000000a.rf

Details about the rfile will be printed. The compression type should match the type used in the compaction.
In this case, `snappy` is used since the size is less than 100M.
