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.
