emrecanagah opened a new issue #7437: [restore data from metadata store] is it possible ? druid ver. 0.13 URL: https://github.com/apache/incubator-druid/issues/7437 Hi, Below is my use-case; I have just deleted some part of my data-source by mistake and I have lost its availability around % 12 . I have been querying coordinator APIs from my console as it shows: curl -X 'GET' 'http://yonett1:8081/druid/coordinator/v1/loadstatus' and the result is {"reporterwifiusage":100.0,"wifiusage":100.0,"activity3":87.79626432271229,"legacyusage1":100.0} curl -X 'GET' 'http://yonett1:8081/druid/coordinator/v1/loadstatus?simple' {"reporterwifiusage":0,"legacyusage1":0,"wifiusage":0,"activity3":1555} When I querying the below command; curl -X 'GET' 'http://yonett1:8081/druid/coordinator/v1/metadata/datasources/activity3/segments?full' I indeed all the metadata segments for this data-source, activity3, as expected and I indeed count all missing segments as 1555. All above operations I performed with fully understand however I can not figure out how I restore my missing 1555 segments from metadata source ? **Is it possible to restore data-source from metadata store information** or is there a way to delete these metadata store information which is not desired at first place ? Btw, I've setup HDFS and use it as the file system in my production cluster. I really need your help. Kind regards, EA
