English Translation: HI I install Java after nifi. In nifi properties, edit the nifi.web.https.host field with the instance's private IP. I start Nifi. I look at the log that popped up. And I put the public IP in the browser. And this error message appears: Could not establish a this site

This time we did show table stats and show column stats on the table before the issue ( just after the restart and before running invalidate metadata) and then after the restart and we do not notice any difference in output but problem reoccurred this time also. To understand the sequence of events : (1) Admin team does patching and restart the cluster (2) application team run a distinct year query and sees out of 31 only 27 rows are present and 4 of the partitions are missing. (3) as a support team, I run show stats which shows all 31 partitions and number of rows in partitions is correct and size also. (4) we run invalidate metadata and refresh (5) support team takes show stats which has same result (6) app team runs they query again and they able to see all 31 partitions. we will work with vendor to get further help.

@Sayed016 This error occurs if the HDFS files are under replicated. Did you see HDFS is under replicated when the issue occurred? Wait for the HDFS to gets replicated and you can query

Often this happens as there is a "hidden" character at the end of the file or folder name. For example a line break (\n, \r, etc). If you list the files you can get a clue that is the case as usually the output will look strange with an extra line or something there. You can try running a few commands like the following to see if it matches a file: hdfs dfs -ls $'/path/to/folder\r' hdfs dfs -ls $'/path/to/folder\n' hdfs dfs -ls $'/path/to/folder\r\n' If any of those match, then you can delete the incorrect one with a similar command. If you get no luck with that, then pipe the ls output into "od -c" and it will show the special characters hdfs dfs -ls /path/to/folder | od -c

Hi @Seaport As you know, resource managers like yarn, standalone, kubernets will create containers. Internally RMs will use shell script to create containers. Based on resources, it will create one or more containers in the same node.
