Difference between a normal hive table and hive table stored as ORC<\/h2>\n\n\n\n\n\n\n\n\n\n

Normal hive table<\/th>\n	Hive table stored as orc<\/th>\n<\/tr>\n
Hive data is organized into Databases: \nNamespaces function to avoid naming conflicts for tables, \nviews, partitions, columns, and so on.<\/td>\n	It produce efficient way to store Hive data.It designed to overcome the drawback of others Hive file formats Using Optimized Row Columnar files improves speed when Hive is reading, writing, and processing data.<\/td>\n<\/tr>\n
Databases can also be used to enforce security for a \nuser or group of users.<\/td>\n	Advantages- Single file as the output of each task, that reduces the NameNode’s load.<\/td>\n<\/tr>\n
There are two types of tables in Hive, \none is Managed table and second is external table. \nThe difference is, when you drop a table, \nif it is managed table hive deletes both data and meta data, \nif it is external table Hive \nonly deletes metadata.<\/td>\n	An Optimized Row Columnar file contains types of data define as stripes,along with information in a file footer. At the end of the file a postscript holds compression parameters and the size of the compressed footer.<\/td>\n<\/tr>\n
It damage how data is loaded, \ncontrolled, and managed in Hive ;By use external \ntables when the data is also used outside of Hive.<\/td>\n	Default stripe size is 250 MB. large stripe sizes enable large, efficient reads from HDFS.<\/td>\n<\/tr>\n
The data files are read and processed by an existing \nprogram that doesn’t lock the files. Data needs to \nremain in the underlying location even after a DROP<\/td>\n	File footer having a list of stripes and number of rows,each columns contains count, min, max, and sum.<\/td>\n<\/tr>\n
Storing data in Hive is nothing but \nstoring data in HDFS (Hadoop).<\/td>\n	The stripe file footer contains a directory of stream locations.Row data is used in table scans<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n","protected":false},"excerpt":{"rendered":" Answer : Hive data is organized into Databases….<\/p>\n","protected":false},"author":2,"featured_media":0,"comment_status":"open","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"passster_activate_protection":false,"passster_protect_child_pages":"","passster_protection_type":"password","passster_password":"","passster_activate_overwrite_defaults":"","passster_headline":"","passster_instruction":"","passster_placeholder":"","passster_button":"","passster_id":"","passster_activate_misc_settings":"","passster_redirect_url":"","passster_hide":"no","passster_area_shortcode":"","gtb_hide_title":false,"gtb_wrap_title":false,"gtb_class_title":"","gtb_remove_headerfooter":false,"footnotes":""},"categories":[3782],"tags":[195,971,3799,203,199,214,209,205,3954,222,484,3959,3952,3953,3794,621,620,196,3716,712,3956,970,366,208,288,3955,483,976,975,200,3958,974,197,280,364,968,216,2119,969],"class_list":["post-584","post","type-post","status-publish","format-standard","hentry","category-hive","tag-accenture-interview-questions-and-answers","tag-altimetrik-india-pvt-ltd-interview-questions-and-answers","tag-ani-technologies-pvt-ltd-interview-questions-and-answers","tag-capgemini-interview-questions-and-answers","tag-casting-networks-india-pvt-limited-interview-questions-and-answers","tag-cgi-group-inc-interview-questions-and-answers","tag-collabera-technologies-interview-questions-and-answers","tag-dell-international-services-india-pvt-ltd-interview-questions-and-answers","tag-different-file-formats-in-hive","tag-flipkart-interview-questions-and-answers","tag-genpact-interview-questions-and-answers","tag-hive-advanced-interview-questions","tag-hive-columnar-storage","tag-hive-file-format-comparison","tag-hive-interview-questions-and-answers-for-experienced","tag-hive-query-based-interview-questions","tag-hive-scenario-based-interview-questions","tag-ibm-interview-questions-and-answers","tag-impetus-technologies-interview-questions-and-answers","tag-indiabulls-technology-solutions-ltd-interview-questions-and-answers","tag-managed-table-vs-external-table-in-hive","tag-mindtree-interview-questions-and-answers","tag-netapp-interview-questions-and-answers","tag-prokarma-softech-pvt-ltd-interview-questions-and-answers","tag-r-systems-interview-questions-and-answers","tag-rc-file-format-in-hive","tag-reliance-industries-ltd-interview-questions-and-answers","tag-synechron-te-interview-questions-and-answers","tag-tata-consultancy-service-interview-questions-and-answers","tag-tech-mahindra-interview-questions-and-answers","tag-text-file-format-in-hive","tag-trigent-software-interview-questions-and-answers","tag-unitedhealth-group-interview-questions-and-answers","tag-virtusa-consulting-services-pvt-ltd-interview-questions-and-answers","tag-wells-fargo-interview-questions-and-answers","tag-wipro-infotech-interview-questions-and-answers","tag-wipro-interview-questions-and-answers","tag-yash-technologies-interview-questions-and-answers","tag-yodlee-infotech-pvt-ltd-interview-questions-and-answers"],"yoast_head":"\n
