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

Just solved such a problem, I have multiple java versions and hadoop3.1.0.

you need to specify the java home variable in etc/hadoop/hadoop-env.sh, and the java version should be 1.8.
