Hi Experts, I have a small question. Due to some deployment on 2 of the Linux servers, Our cluster's Key Trustee KMS & Key Trustee Server will have a downtime of few minutes during server reboot. I want to know what would be the impact on Hadoop services, since there is continuous data ingestion and extraction. So if there is an impact then we can stop the service and also inform others.

Hello All, We have been informed to migrate from LDAP to LDAPS. Hence we are changing the configuration from ldap to ldaps in hue and hive as already we have SSL/TLS enabled, But I do have one question in hdfs configuration it as set hadoop.rpc.protection = authentication. So we thought of making changes to this as well by changing it from authentication to privacy. What is the suggestion regarding this, is it the best practice what we are planning to do or should we keep the same as authentication. Is there any impact after the change.

@tusharkathpal Thanks for the explanation. Are you sure there is no other way to know the size of the view table. I tried with hdfs dfs -ls command but we have tables in partition so not able to locate the exact table. I can check the size by running hdfs dfs -du -s -h on the path on different directories and sub directories. A quick reply will be highly appreciated.

Hello, I am unable to know the size of the hive table. Actually it is a view specifically which we wanted to know the size of. I have tried by running commands such as hdfs dfs -du -s -h /path/to/table, but the view can't be found in the location. beeline> describe formatted/extended table name; Also does not give the output I also tried with ANALYZE but no output as well. Can some one tell me how to know the size of the view table. Since we have created view of the different table in database. And we want to know the size of the particular table.
