> Currently SentryAuthorizationProvider rejects setter calls to Sentry-managed paths, and
issue an error message when enabled.
> There are two issues:
> 1. When creating a file or dir, the parent dir's group will be set to the newly created
file/dir, this is supposed to be logged to fsimage in-memory representation, but because the
rejection of Sentry, it's not.
> 2. (as an example) When user issue a setOwner call via the following RPC:
> {code}
> @Override // ClientProtocol
> public void setOwner(String src, String username, String groupname)
> throws IOException {
> checkNNStartup();
> namesystem.setOwner(src, username, groupname);
> }
> {code}
> Two calls are executed in the deep stack:
> {code}
> a. dir.setOwner(src, username, group);
> b. getEditLog().logSetOwner(src, username, group);
> {code}
> The first call is the one gets rejected by Sentry, however, the second one still updates
the entry to Edit log. This would indicate an inconsistency between in-memory representation
of the attribute and what's recorded on edit log.
> Creating this jira to make SentryAuthorizationProvider always fallthrough to write to
HDFS, and issue a warning msg when it "rejects" (for Sentry-managed paths).
