> [Azure Data Lake] Support for process level FileStatus cache to optimize
> GetFileStatus frequent opeations
> ---------------------------------------------------------------------------------------------------------
>
> Key: HADOOP-12876
> URL: https://issues.apache.org/jira/browse/HADOOP-12876
> Project: Hadoop Common
> Issue Type: Improvement
> Components: fs, fs/azure, tools
> Reporter: Vishwajeet Dusane

>
> Add support to cache GetFileStatus and ListStatus response locally for
> limited period of time. Local cache for limited period of time would optimize
> number of calls for GetFileStatus operation.
> One of the example where local limited period cache would be useful -
> terasort ListStatus on input directory follows with GetFileStatus operation
> on each file within directory. For 2048 input files in a directory would save
> 2048 GetFileStatus calls during start up (Using the ListStatus response to
> cache FileStatus instances).
