Hi,    we have a 3 datanode hadoop cluster (CDH 5.10). the replication factor is set to 2.  now we cannot access data from Hbase table due to failed regions on that table. could somebody can give me some suggestion to fix this issue(we don't lost data)?      the failed regions are in "Regions in Transition" state. we tried to fix and repair the table by below command.         $ hbase hbck -fix <table> $ hbase hbck -repair <table>             But failed, we got error like below:           21/02/08 02:03:33 INFO util.HBaseFsck: Checking and fixing region consistency ERROR: Region { meta => xxxxLogsIndexer,,1588737167917.327a6ed6b00c95e63346f6d725147952., hdfs => hdfs://cdh-cm.test.com:8020/hbase/data/default/xxxxLogsIndexer/327a6ed6b00c95e63346f6d725147952, deployed => , replicaId => 0 } not deployed on any region server.
