Íñigo Goiri commented on HDFS-6874:
-----------------------------------
The reason I found this JIRA was because I was adding a explorer UI to HttpFS.
While doing so, I had issues with GET_BLOCK_LOCATIONS.
The problem is that explorer.js relies on it to show each of the blocks.
With the current WebHDFS interface this is not possible as it doesn't show
block ids.
Internally, I ended up implementing GET_BLOCK_LOCATIONS by using the DFSClient
but it's pretty ugly.
I'd love to get a unified view.
Minor comments on [^HDFS-6874.09.patch]:
* Let's use the logger format {}.
* We are adding GET_BLOCK_LOCATIONS to HttpFSParametersProvider but it is not
implemented in HttpFSServer.
> Add GETFILEBLOCKLOCATIONS operation to HttpFS
