Contributed by Thomas Marquardt DETAILS: WASB depends on the Azure Storage Java SDK. There is a concurrency bug in the Azure Storage Java SDK that can cause the results of a list blobs operation to appear empty. This causes the Filesystem listStatus and similar APIs to return empty results. This has been seen in Spark work loads when jobs use more than one executor core. See Azure/azure-storage-java#546 for details on the bug in the Azure Storage SDK. TESTS: A new test was added to validate the fix. All tests are passing: wasb: mvn -T 1C -Dparallel-tests=wasb -Dscale -DtestsThreadCount=8 clean verify Tests run: 248, Failures: 0, Errors: 0, Skipped: 11 Tests run: 651, Failures: 0, Errors: 0, Skipped: 65 abfs: mvn -T 1C -Dparallel-tests=abfs -Dscale -DtestsThreadCount=8 clean verify Tests run: 64, Failures: 0, Errors: 0, Skipped: 0 Tests run: 437, Failures: 0, Errors: 0, Skipped: 33 Tests run: 206, Failures: 0, Errors: 0, Skipped: 24 |
