> [ABFS]: FooterReadBufferSize should not be greater than readBufferSize

>                 Key: HADOOP-19102
>                 URL: https://issues.apache.org/jira/browse/HADOOP-19102
>             Project: Hadoop Common
>          Issue Type: Sub-task
>          Components: fs/azure
>            Reporter: Pranav Saxena
>            Assignee: Pranav Saxena
>            Priority: Major
>              Labels: pull-request-available
>             Fix For: 3.4.0, 3.5.0
>
>
> The method `optimisedRead` creates a buffer array of size `readBufferSize`. 
> If footerReadBufferSize is greater than readBufferSize, abfs will attempt to 
> read more data than the buffer array can hold, which causes an exception.
> Change: To avoid this, we will keep footerBufferSize = 
> min(readBufferSizeConfig, footerBufferSizeConfig)
>
