We have CDH5.9.2 hadoop 13-node cluster and from one week, I am exeperiencing block count concerning warning notification in cloudera manager for all 6 datanodes.
We have multitenancy implemented in our cluster. So I deleted the older files via hdfs command line and block count is below the threshold value.
But still the block count concerning warning appears in the cloudera manager.
