Suresh, you can "reinitialize" Accumulo by doing the following:
* Stop Accumulo
* Run `hdfs dfs -rm -R -skipTrash /apps/accumulo/data` (assuming you're
using HDP as you linked the HDP documentation).
* Re-run `accumulo init`
* Start Accumulo
If you are on HDP (notably, using Ambari), you likely need to provide
some extra arguments to ensure Accumulo is configured as Ambari expects.
You can find a write-up at [1]
However, like Dylan points out, you don't need to use the "heavy-hammer"
to delete all of HDFS. Just drop the Accumulo tables you don't want next
time.

Hello Team
I want to clear all records in accumulo for my local machine and want to
delete unused tables created while testing. I found delete table command
which can be used from accumulo shell however that will require much of
manual works for deleting large number of tables. I also tried instructions
<https://docs.hortonworks.com/HDPDocuments/HDP2/HDP-2.4.2/bk_installing_manually_book/content/format_and_start_hdfs.html>
to
format namenode of hadoop but that doesn't seems to work. My question is
how can I remove all tables and have fresh start with accumulo datastore?
Any suggestion is welcomed. Tons of thanks in advanced.
Thank You
