@Tarun Parimi Hi Tarun, thanks for the reply. It helped and gave confidence. We simulated the same in development and upon confirmation we went ahead with production. I was surprised to see the namenode service on standby NN getting restarted when we run this metadataVersion command. I feel this was just an informational command & the output was quite similar to namenode format command though it takes arguement as metadataversion. Hortonworks should have improved the output descriptions instead of just being general like "Block deletion will happen in 1 hr" (atleast they can put like only corrupted block deletion). Also unsure why it is restarting the namenode service which inturn takes the "dfs.namenode.startup.delay.block.deletion.sec" parameter and displays those information. ... View more

Hi @Muthukumar S! What happens if you run the following command? (*change the dfs.nameservices above for the respective value) hdfs dfs -ls hdfs://<dfs.nameservices>/user And also you can try to run the following command hdfs namenode -recover https://hadoop.apache.org/docs/r2.7.1/hadoop-project-dist/hadoop-hdfs/HDFSCommands.html#namenode Hope this helps ...

@Sindhu The 6 mounts are like /data0, /data1, /data2, /data3, /data4, /data5 and new mount will be like /eim_data0 & /eim_data1. Under /data0 to 5, the folder structures are same with many sub directories and final files are different. If i copy /data0 all data to /eim_data0 and when i copy /data1 to the same place then it will overwrite the existing directories as they are same. Can i do in a below way? copy /data0 to /eim_data0/data0/ copy /data1 to /eim_data0/data1/ copy /data2 to /eim_data0/data2/ & same way data3, 4, 5 to eim_data1/data3 eim_data1/data4 eim_data1/data5 and mention these 6 directories in the hdfs configurations. Will it cause any issue or is this fine? ... View more
