hbase - Deleting all data and metrices from OpenTSDB -

i made 2 metrices in opentsdb test purpose using command:

./build/tsdb mkmetric temperatures ./build/tsdb mkmetric meterreadings 

i entered datapoints in these metrices using java:

put temperatures 1356998400 23.5 room=bedroom floor=1\n put meterreading 1430568000 32800 accumulationbehaviour=4 commodity=1 dataqualifier=12 defaultquality=0 flowdirection=1 intervallength=900 intervallength=900 kind=12 phase=769 poweroftenmultiplier=0 timeattribute=0 uom=72 put meterreading 1430568900 33624 accumulationbehaviour=4 commodity=1 dataqualifier=12 defaultquality=0 flowdirection=1 intervallength=900 intervallength=900 kind=12 phase=769 poweroftenmultiplier=0 timeattribute=0 uom=72 put meterreading 1430569800 35192 accumulationbehaviour=4 commodity=1 dataqualifier=12 defaultquality=0 flowdirection=1 intervallength=900 intervallength=900 kind=12 phase=769 poweroftenmultiplier=0 timeattribute=0 uom=72 put meterreading 1430570700 37928 accumulationbehaviour=4 commodity=1 dataqualifier=12 defaultquality=0 flowdirection=1 intervallength=900 intervallength=900 kind=12 phase=769 poweroftenmultiplier=0 timeattribute=0 uom=72 

now want delete data , metrices, opentsdb behave fresh installation.

in documentation mention using scan command, not sure how use command.

it well-written in opentsdb website. also, have google group has written answer it.

syntax:

scan [--delete|--import] start-date [end-date] query [queries...]

examples:

tsdb scan --delete 1970/01/01-00:00:00 sum temperatures

tsdb scan --delete 1970/01/01-00:00:00 sum meterreadings

if want specify zookepeer: tsdb scan --delete --zkquorum localhost 1970/01/01 min temperatures 

this delete data stored in tsdb table. think doesn't delete entry tsdb-uid table. can rename metric name new name.

`tsdb uid rename metrics old.name new.name`
