Ayush Saxena commented on HDFS-15516:
-------------------------------------
Thanx everyone, from the compatibility point of view, This is indeed
incompatible, we can't change things in between, As [~csun] mentioned this is
going to break the parsers.
>From the compatibility guidelines :
{noformat}
Several components have audit logging systems that record system
information in a machine readable format. Incompatible changes to that
data format may break existing automation utilities. For the audit log,
an incompatible change is any change that changes the format such that
existing parsers no longer can parse the logs.
Policy
All audit log output SHALL be considered Public and Stable. Any change to the
data format SHALL be considered an incompatible change.{noformat}
Though good to have, but I think we can't/shouldn't do this,
{{Create}}/{{Append}}/{{Rename}} these are quite high frequency calls as well.

> Currently, if file create happens with flags like overwrite , the audit logs
> doesn't seem to contain the info regarding the flags in the audit logs. It
> would be useful to add info regarding the create options in the audit logs
> similar to Rename ops.
