Unable to copy file from Local directory to HDFS


Unable to copy file from Local directory to HDFS



I have formatted the Namenode, permissions on HDFS directories, but it didn't help me. I am running a single node hadoop cluster on ubuntu. This is the error I am facing:


java.io.IOException: File /mydir could only be replicated at 0 nodes, instead of 1.



Any help or guidance about where to look and how to solve this error.





Could you please provide a bit more detail, how are you getting this error, do you have any code associated with the issue?

This error is generated when your datanode is down, or when it is up but not able to connect with the Namenode

Look at the Hadoop logs directory. Open the datanode logs look for errors. Run jps, look for datanode

Export result set on Dbeaver to CSV

Export result set on Dbeaver to CSV Normally I use Dbeaver for windows and always export my result set like this: run my query --> select the result --> export the result set --> select export to clipboard --> done This step by step puts my result set in my clipboard and I can paste it wherever I want to work with it. The problem is that now I am using dbeaver for mac and this guide is not working. I can go on until the moment that I select my result set like in the image below: exporting data set But once I go further in the process, in the last step I get: no query Note that in "source" it was suppose to show the query that originated the result set, but instead it says just "select.

Normally my query would show up there automatically and I couldn't find any option that corrects this problem in the menus. Please help me! Thanks. Aft...
