> [HDFS] [RBF] Guava cache performance issue in Router MountTableResolver
> -----------------------------------------------------------------------
>
> Key: HDFS-16257
> URL: https://issues.apache.org/jira/browse/HDFS-16257
> Project: Hadoop HDFS
> Issue Type: Improvement
> Affects Versions: 2.10.1
> Reporter: Janus Chow
> Assignee: Janus Chow
> Priority: Major
> Labels: pull-request-available
> Time Spent: 1h
> Remaining Estimate: 0h

> Branch 2.10.1 uses guava version of 11.0.2, which has a bug which affects the
> performance of cache, which was mentioned in HDFS-13821.
> Since upgrading guava version seems affecting too much, this ticket is to add
> a configuration setting when initializing cache to walk around this issue.
