Error “Failed to retrieve data from /webhdfs/v1/?op=LISTSTATUS: Server Error” when using hadoop

Question

I opened up localhost:9870 and try to upload a txt file to the hdfs.

I see the error message below

Failed to retrieve data from /webhdfs/v1/?op=LISTS         


        

Answer 1

I got this to work with OpenJDK 13 by downloading hadoop 2.9.2 and copying the activation-1.1.jar file from that download into the $HADOOP_HOME/share/hadoop/yarn folder you're using for Hadoop 3. Then you have to run stop-dfs.sh and stop-yarn.sh and then start them both again. No need to edit any config files with this method since it will automatically be added to the classpath.
