By default, it will return all the regions for the table with any locality. The command displays server name, region name, start key, end key, size of the region in MB, number of requests and the locality. The information can be projected out via an array as third parameter. By default all these information is displayed. Possible array values are SERVER_NAME, REGION_NAME, START_KEY, END_KEY, SIZE, REQ and LOCALITY. Values are not case sensitive. If you don't want to filter by server name, pass an empty hash / string as shown below. Examples: hbase> list_regions 'table_name' hbase> list_regions 'table_name', 'server_name' hbase> list_regions 'table_name', {SERVER_NAME => 'server_name', LOCALITY_THRESHOLD => 0.8} hbase> list_regions 'table_name', {SERVER_NAME => 'server_name', LOCALITY_THRESHOLD => 0.8}, ['SERVER_NAME'] hbase> list_regions 'table_name', {}, ['SERVER_NAME', 'start_key'] hbase> list_regions 'table_name', '', ['SERVER_NAME', 'start_key'] hbase(main):005:0> list_regions 'cluster_test' SERVER_NAME | REGION_NAME | START_KEY | END_KEY | SIZE | REQ | LOCALITY | --------------------------- | ---------------------------------------------------------------------------------------------------- | --------------------------------------- | --------------------------------------- | ----- | -------- | ---------- | nokedli,34665,1582736360668 | cluster_test,,1582878981608.614acededc61f55a10816bb871d0421b. | | 197f83f2390a2a0c4104f4630982c585-461828 | 3348 | 10204021 | 0.0 | nokedli,34665,1582736360668 | cluster_test,197f83f2390a2a0c4104f4630982c585-461828,1582878981608.5987f972793bd422564a0758e545caa5. | 197f83f2390a2a0c4104f4630982c585-461828 | 33333333 | 3348 | 10204021 | 0.0 | nokedli,34665,1582736360668 | cluster_test,33333333,1582878982425.a306381f3ee03161dc832eaca066131b. | 33333333 | 4cdfa653a3843d49a62004a6e4e71636-501997 | 3321 | 10121061 | 0.0 | nokedli,34665,1582736360668 | cluster_test,4cdfa653a3843d49a62004a6e4e71636-501997,1582878982425.ae87e47584e3dee98e524f961fa6906e. | 4cdfa653a3843d49a62004a6e4e71636-501997 | 66666666 | 3321 | 10121061 | 0.0 | nokedli,34665,1582736360668 | cluster_test,66666666,1582878983449.d4015a18e47a9aeec89a1ead9a974186. | 66666666 | 7ffd66580ac07b1ff7636f9b15609fa6-238805 | 3316 | 10107887 | 0.0 | nokedli,34665,1582736360668 | cluster_test,7ffd66580ac07b1ff7636f9b15609fa6-238805,1582878983449.c92f8a7b3a89fee59313bdb516720319. | 7ffd66580ac07b1ff7636f9b15609fa6-238805 | 99999999 | 3316 | 10107887 | 0.0 | nokedli,34665,1582736360668 | cluster_test,99999999,1582878984099.36d0e3d56119f2bdcae280853c29321d. | 99999999 | b36cb3f90c3019779ba5a3b00fb6da2f-320789 | 3327 | 10142656 | 0.0 | nokedli,34665,1582736360668 | cluster_test,b36cb3f90c3019779ba5a3b00fb6da2f-320789,1582878984099.9d76372540e628675a4aea5a8979107d. | b36cb3f90c3019779ba5a3b00fb6da2f-320789 | cccccccc | 3327 | 10142656 | 0.0 | nokedli,34665,1582736360668 | cluster_test,cccccccc,1582878984966.1292a5f5dbd5f454d5d3b3cf048c4a75. | cccccccc | e66d48d7b227e7845b73d43eb1a06fcb-86032 | 3355 | 10225734 | 0.0 | nokedli,34665,1582736360668 | cluster_test,e66d48d7b227e7845b73d43eb1a06fcb-86032,1582878984966.6765ff09c59899363ae9be115a9c3d78. | e66d48d7b227e7845b73d43eb1a06fcb-86032 | | 3355 | 10225734 | 0.0 | 10 rowshbase(main):006:0>
