ilooner commented on issue #1296: DRILL-5365: Prevent plugin config from
changing default fs. Make DrillFileSystem Immutable.
URL: https://github.com/apache/drill/pull/1296#issuecomment-406743060
@sohami Thanks for saving the day on this PR and pointing out the issues
before the changes got merged. With the flaws you pointed out, I think my
proposed solution has been debunked. There was one other possible source of the
issue I identified earlier, but thought was less likely.
"FileSystemConfigurations defined in the HiveStoragePlugin are passed to
DrillFileSystem in HiveDrillNativeParquetRowGroupScan.getFsConf(). "
I will explore that possible bug, and try to replicate an error scenario in
a unit test. If I find anything I will update this PR with a fix for that
issue. If that is not a viable bug, I will repurpose this PR to only enforce
the immutability of DrillFileSystem and include no additional changes.
Thanks again!
