Walter Su commented on HDFS-9337:
---------------------------------
{noformat}
curl -i -X POST
"http://<HOST>:<PORT>/webhdfs/v1/<PATH>?op=CONCAT&sources=<PATHS>"
{noformat}
throws not user-friendly stacktrace when missing {{sources}}
{noformat}
curl -i -X PUT "http://<HOST>:<PORT>/webhdfs/v1/<PATH>?op=SETXATTR
&xattr.name=<XATTRNAME>&xattr.value=<XATTRVALUE>
&flag=<FLAG>"
{noformat}
throws NPE when missing XATTRNAME. And {{xattr.value}} acually is not required,
so document is wrong in this case.
That's fix the same issues together, shall we? I haven't found other NPEs. I'll
appreciate if you could check again all the required params per documentation.
> Should check required params in WebHDFS to avoid NPE
