Hello Need your help regarding the hive metastore. we are using cdh 5.14 cluster with hive and other services, we are facing issue with hive metastore. Every week our hive metastore goes in bad health with alert shows "canary status bad". when we checked logs of HMS there is nothing suspected. we have given 78G of mem to the host when we check the host memory on HMS host  it shows near about 23G physical memory used but it shows the chaches memory used 53 G Any suggestion on this issue. - If we do HMS HA, Is it possible both the HMS work parallelly if yes how we can achieve this? Thanks Shahezad   ... View more
