-----------------------------------------------------------------
Thanks for the patch. In addition to [~ljain]'s comment here are a few more:
# Make sense to use PUT method for allowSnapshot/disallowSnapshot
# Like HDFS-13916, once HADOOP-15691 completes we should use PathCapabilities
instead.
# We can improve this message "allowSnapshot is only supported on
DistributedFileSystem".
Can we log "allowSnapshot is not supported for HttpFs on " + fs.getClass() + ".
Please check your fs.defaultFS configuration"? This'll help make
troubleshooting easier.
