> This violates Accumulo's durability guarantees when using the default SYNC durability setting. I think there is a misunderstanding of the durability guarantee. There was a recent change and related discussion revolving around durability at https://github.com/apache/accumulo/pull/5988. Accumulo is currently limited to using Hadoop Compatible File Systems. The FileSystem that is being used (and maybe the options within the FileSystem) will dictate whether or not `sync` actually works. As we have discussed the differences between RawLocalFileSystem and LocalFileSystem, it's likely the case that other FileSystem implementations don't support `flush` or `sync`. I'm pretty sure that the `S3` filesystem do not support `sync`. Additionally, even when using the DistributedFileSystem (HDFS) implementation, erasure coded files do not support `sync` either. -- This is an automated message from the Apache Git Service.
