Hi @iamfromsky , Thank you for reaching out to our community! The error message which you have provided is logged when either a "broken pipe" or "connection reset" happens, which is most likely network-related. Please check if the network is stable when you see these errors. Also refer Jira HDFS-8814 for more details.

Hi @regeamor, Thank you for reaching out to community! The DistCp command submits a regular MapReduce job that performs a file-by-file copy. The block locations of the file is obtained from the name-node during MapReduce. On DistCp, each Mapper will be initiated, if possible, on the node where the first block of the file is present. In cases where the file is composed of multiple splits, they will be fetched from the neighbourhood if not available on the same node. The fs.s3a.fast.upload option significantly accelerates data upload by writing the data in blocks, possibly in parallel. Please refer on How to improve performance for DistCp for more details.

Hi @shrikant_bm , When ever Active NameNode server goes down, its associated daemon also goes down. HA works in the same way whenever Active NameNode daemon or server goes down. ZKFC will not receive the heartbeat and the ZooKeeper session will expire, notifying the other NameNode that a failover should be triggered. To answer your question: yes, in both the cases mentioned by you, HA should work.

Hi @shrikant_bm , Please find answers inline. 1. When active namenode server is rebooted will the standby namenode will not become active? Is this something expected? Or Did the HA did not work in our cluster Yes, standby NameNode will become active when primary NameNode reboots, provided high availability is enabled and configured. 2. Whether the HA is expected to work only between the active and standby namenode daemons? Yes, HA works only between active and standby NameNode. It is taken care by ZKFC (ZooKeeper Failover Controller).
