Kai Zheng commented on HDFS-7349:
---------------------------------
Thanks Vinay for the detailed clarifying.
About convertToEC command, I had an offline discussion with Vinay and we're
synced as follows.
Like createZone command, we also need an option/parameter to specify the schema
name to be used for the conversion. It's optional, when not specified, a system
default schema (can be configured) will be used. The specified or default
schema will be used to erasure code the converted individual folder/file.
> Support DFS command for the EC encoding
