Vinayakumar B commented on HDFS-8090:
-------------------------------------
bq. FSNamesystem#getECSchemas - do we need audit log here? Actually I got
confused after going through the existing logs, it looks like audit log has
been done for getter calls also. For example, getEZForPath, getfileinfo,
listStatus et.
IMO audit log not required for this call as this is systemwide call. not
particular to any path. all the above calls referred are have a path.
Similar to this call is {{getStoragePolicies()}} which also doesnt have audit
log.
> Erasure Coding: Add RPC to client-namenode to list all ECSchemas loaded in
> Namenode.

> ECSchemas will be configured and loaded only at the Namenode to avoid
> conflicts.
> Client has to specify one of these schemas during creation of ecZones.
> So, add an RPC to ClientProtocol to get all ECSchemas loaded at namenode, so
> that client can choose only any one of these.
