Thanks Neeraj and Josh. Finally this command worked for me after Changing the desired state to 'installed' in hostcomponentdesiredstate,servicedesiredstate and servicecomponentdesiredstate tables for component_name like 'accumulo%' curl --user admin:admin -i -H "X-Requested-By: ambari" -X DELETE http://`hostname -f`:8081/api/v1/clusters/cl1/services/ACCUMULO Here is the error I got before updating the tables and after running the command.

Thanks. The accumulo services are not starting, so I'm trying to delete accumulo service from Ambari, but delete was disabled from drop down menu. Any advise? accumulo-error.png

Thanks Artem and Neeraj. I just copied the data from /apps/hive/warehouse to a local directory. Note: Hive data is not necessary located in the folder
mentioned above. i.e. external table can be defined anywhere within the HDFS. hive –e “DESCRIBE
FORMATTED <tablename>” > <tablename_descformat>.txt; This
command is to collect detail information of tables. The detail information for a table includes column,
partition, database it belongs, owner, create time, last access time, protect
mode, location, table type, storage information and etc.

Can anyone let me know how to use Sqoop to export data from Hive to a flat file to be picked up by Hive again? I understand that Sqoop can export data to tables, however I have a scenario where I want to export data into flat files
