@steveloughran i also tested the entire test suite by enabling prefatch. Tests in ITestS3AContractVectoredRead failed. One example:

[ERROR] testMinSeekAndMaxSizeDefaultValues[Buffer type : direct](org.apache.hadoop.fs.contract.s3a.ITestS3AContractVectoredRead)  Time elapsed: 13.025 s  <<< FAILURE!
org.junit.ComparisonFailure: [Mismatch in default s3a min seek for vectored reads] expected:<4[8]96> but was:<4[0]96>

	at org.apache.hadoop.fs.contract.s3a.ITestS3AContractVectoredRead.testMinSeekAndMaxSizeDefaultValues(ITestS3AContractVectoredRead.java:111)

However, the failures don't seem relevant to the change on this PR. As per the test logic, it seemsITestS3AContractVectoredRead failures are expected when prefetch is enabled.

steveloughran · 2022-08-25T10:04:28Z

hadoop-tools/hadoop-aws/src/main/java/org/apache/hadoop/fs/s3a/S3AFileSystem.java

    unboundedThreadPool.allowCoreThreadTimeOut(true);
    executorCapacity = intOption(conf,
        EXECUTOR_CAPACITY, DEFAULT_EXECUTOR_CAPACITY, 1);
    if (this.prefetchEnabled) {


can you cut the this. from here and the line below. not something we do in the hadoop code except in constructors and setters

sounds good, done

+1 looks good, Only suggestion is maybe a test in prefetch IT to verify the duration for executor acquisition we do in SemaphoredDelegatingExecutor for input stream IOStats.

@steveloughran @mehakmeet could you please take another look?

i'm letting mehakmeet review this

mehakmeet

+1, just a small doubt on the assertion.

mehakmeet · 2022-09-06T09:53:47Z

...-tools/hadoop-aws/src/test/java/org/apache/hadoop/fs/s3a/ITestS3APrefetchingInputStream.java

    }
    // Verify that once stream is closed, all memory is freed
    verifyStatisticGaugeValue(ioStats, StreamStatisticNames.STREAM_READ_ACTIVE_MEMORY_IN_USE, 0);
+    assertDurationRange(ioStats, StoreStatisticNames.ACTION_EXECUTOR_ACQUIRED, 0, 10);


This would pass for the duration of acquisition executor=0 as well. Think having an assertThat.isGreaterThan(0) should be fine as well.
