> Intermittent test timeout for
> ITestAbfsInputStreamStatistics#testReadAheadCounters happening due to race
> conditions in readAhead threads.
> Test error:

> [ERROR]
> testReadAheadCounters(org.apache.hadoop.fs.azurebfs.ITestAbfsInputStreamStatistics)
> Time elapsed: 30.723 s <<<

> Possible Reasoning:
> - ReadAhead queue doesn't get completed and hence the counter values are not
> satisfied in 30 seconds time for some systems.
> - The condition that readAheadBytesRead and remoteBytesRead counter values
> need to be greater than or equal to 4KB and 32KB respectively doesn't occur
> in some machines due to the fact that sometimes instead of reading for
> readAhead Buffer, remote reads are performed due to Threads still being in
> the readAhead queue to fill that buffer. Thus resulting in either of the 2
> counter values to be not satisfying the condition and getting in an infinite
> loop and hence timing out the test eventually.
> Possible Fixes:
> - Write better test(That would pass under all conditions).
> - Maybe UT instead of IT?
> Possible fix to better the test would be preferable and UT as the last resort.
