> URL: https://issues.apache.org/jira/browse/HBASE-27046
> Project: HBase
> Issue Type: Improvement
> Reporter: Duo Zhang
> Assignee: Duo Zhang
> Priority: Major
>
> This is the current code
> {code}
> /**
> * retrieve the next path to use for writing. Increments the internal
> filenum.
> */
> private Path getNewPath() throws IOException {
> this.filenum.set(EnvironmentEdgeManager.currentTime());
> Path newPath = getCurrentFileName();
> while (fs.exists(newPath)) {
> this.filenum.incrementAndGet();
> newPath = getCurrentFileName();
> }
> return newPath;
> }
> {code}
> In some tests, we inject our own EnvironmentEdge, it may return the same ts
> always or even go backwards, the logic here is not rnough to keep the filenum
> monotone increasing, as we may have already archive the old file.
