> [ABFS] Implement Backoff and Read Footer metrics using IOStatistics Class
> -------------------------------------------------------------------------
>
> Key: HADOOP-19311
> URL: https://issues.apache.org/jira/browse/HADOOP-19311
> Project: Hadoop Common
> Issue Type: Task
> Components: fs/azure
> Affects Versions: 3.5.0, 3.4.1
> Reporter: Manish Bhatt
> Assignee: Manish Bhatt
> Priority: Major
> Labels: pull-request-available
>
> Current Flow: We have implemented metrics collection in ABFS flow. We have
> created a custom AbfsBackoffMetrics and AbfsReadFooterMetrics class which
> stores all the metrics on the file system level. Our objective is to move
> away from the custom class implementation and use IOStatisticsStore to store
> the metrics which is present in hadoop-common.
> Changes Made: This PR contains the changes related to storing metrics related
> to above mentioned classes in IOStatisticStore which is present in
> hadoop-common. AbstractAbfsStatisticsSource abstract class is created which
> is implementing IOStatisticsSource interface. This will store IOStatistics of
> the child metrics class.
> Both AbfsBackoffMetrics and AbfsReadFooterMetrics is inheriting
> AbstractAbfsStatisticsSource and store the respective metrics in
> IOStatisticsStore.
