I cannot transfer the file to Hadoop. Below I add the commands that I have used and the obtained error.
Command 1:
curl -i -X PUT "http://myip:50070/webhdfs/v1/tmp/tempForTest.txt?user.name=hadoop&op=CREATE&overwrite=false&createparent=false&replication=1&permission=777"

See second step to creating a file
curl -i -X PUT -T <LOCAL_FILE>
You're missing a -T, and it's taking your file as a URL, which is malformed, therefore the error
