---------------------------------
Assignee: Duo Zhang
> Optimize FSTableDescriptors.get to not always go to fs when cache miss
> ----------------------------------------------------------------------
>
> Key: HBASE-24949
> URL: https://issues.apache.org/jira/browse/HBASE-24949
> Project: HBase
> Issue Type: Improvement
> Components: master
> Reporter: Duo Zhang
> Assignee: Duo Zhang
> Priority: Major
>
> Since in the below getAll method, if fsvisited is true, we will just return
> what we have in cache.
> We should also do this in the get method, if fsvisited is true, we do not
> need to go to fs any more.
> Another benefit here is that, when executing procedures on master, we do not
> need to go to meta region any more, we could just check if we have a table
> descriptor in cache.
