------------------------------------
Status: Patch Available (was: Open)
> Intermittent Failures in TestHashContent
> ----------------------------------------

> Key: NIFI-10989
> URL: https://issues.apache.org/jira/browse/NIFI-10989
> Project: Apache NiFi
> Issue Type: Bug
> Reporter: David Handermann
> Assignee: David Handermann
> Priority: Blocker
> Time Spent: 10m
> Remaining Estimate: 0h

> The {{TestHashContent.testSHA1}} method fails intermittently on GitHub
> automated builds, and also fails consistently when running as an individual
> test class with the following error:
> {noformat}
> Error: Tests run: 3, Failures: 1, Errors: 0, Skipped: 0, Time elapsed: 0.063
> s <<< FAILURE! - in org.apache.nifi.processors.standard.TestHashContent
> Error: org.apache.nifi.processors.standard.TestHashContent.testSHA1 Time
> elapsed: 0.016 s <<< FAILURE!
> org.opentest4j.AssertionFailedError:
> Processor has 1 validation failures:
> 'Hash Algorithm' validated against 'SHA-1' is invalid because Given value not
> found in allowed set 'SHA3-512, SHA-384, SHA, SHA3-384, SHA-224, SHA-512/256,
> SHA-256, MD2, SHA-512/224, SHA3-256, SHA-512, MD5, SHA3-224'
> {noformat}
> The problem is the result of {{Security.getAlgorithms("MessageDigest")}}
> returning different results in different scenarios. The standard JDK returns
> {{SHA}} but the Bouncy Castle Security Provider returns {{SHA-1}}. In some
> Maven builds, other classes invoke {{Security.addProvider(new
> BouncyCastleProvider())}} which changes the registered security providers for
> the entire Java Runtime. This allows the current test method to run
> successfully. In scenarios where the Bouncy Castle Provider is not
> registered, the test fails.
> The {{HashContent}} Processor is deprecated in favor of
> {{CryptographicHashContent}} and will be removed in subsequent major
> releases. Although one solution would involve registering the Bouncy Castle
> Provider, removing the test method avoids intermittent failures and
> simplifies future maintenance with impending removal the Processor.
