Hello Hive timestamp does support up to 9 digits decimal places (nano seconds) For your case, maybe you can check whether for those timestamp with none-zero nano seconds, e.g. 1750-01-01 00:00:00.123456789, whether such data can be exported correctly And for your example, 00:00:00.0 equals to 00:00:00, you didn't lose any precision, as it is zero nanosecond

Hello According to the documentation related to the state management, it will only pull the new files compared to last run https://nifi.apache.org/docs/nifi-docs/components/org.apache.nifi/nifi-azure-nar/1.5.0/org.apache.nifi.processors.azure.storage.ListAzureBlobStorage/ State management: Scope Description CLUSTER After performing a listing of blobs, the timestamp of the newest blob is stored. This allows the Processor to list only blobs that have been added or modified after this date the next time that the Processor is run. State is stored across the cluster so that this Processor can be run on Primary Node only and if a new Primary Node is selected, the new node can pick up where the previous node left off, without duplicating the data.

Hello This is related to the Cache Management of HDFS As described in the documentation: https://hadoop.apache.org/docs/current/hadoop-project-dist/hadoop-hdfs/CentralizedCacheManagement.html In this architecture, the NameNode is responsible for coordinating all the DataNode off-heap caches in the cluster. The NameNode periodically receives a cache report from each DataNode which describes all the blocks cached on a given DN. The NameNode manages DataNode caches by piggybacking cache and uncache commands on the DataNode heartbeat. If the metric is going up, one possibility could be your namenode is too busy to handle the request
