[HADOOP-18475] ITestS3AInputStreamPerformance#testDecompressionSequential128K NPE if no CSV file available

• Type: Sub-task
• Status: Open
• Priority: Minor
• Resolution: Unresolved
• Component/s: fs/s3

Environment

Third party store.

These are relevant auth-keys configs - probably an uncommon combination:

<property>
    <name>fs.s3a.scale.test.enabled</name>
    <value>true</value>
</property>

<property>
    <name>fs.s3a.scale.test.csvfile</name>
    <value> </value>
</property>

Description

I am running the integration tests against a store with no CSV file available for scale testing. (scale enabled, csv empty).

NPE is here: https://github.com/apache/hadoop/blob/682931a6ace460d829954398eddecefeeac82b34/hadoop-tools/hadoop-aws/src/test/java/org/apache/hadoop/fs/s3a/scale/ITestS3AInputStreamPerformance.java#L397

We should add a call to this somewhere - not entirely sure where right now: https://github.com/apache/hadoop/blob/682931a6ace460d829954398eddecefeeac82b34/hadoop-tools/hadoop-aws/src/test/java/org/apache/hadoop/fs/s3a/scale/ITestS3AInputStreamPerformance.java#L166-L171
