Description

I occasionally get the following failure:

-------------------------------------------------------------------------------
Test set: org.apache.accumulo.test.performance.metadata.FastBulkImportIT
-------------------------------------------------------------------------------
Tests run: 1, Failures: 1, Errors: 0, Skipped: 0, Time elapsed: 64.649 sec <<< FAILURE! - in org.apache.accumulo.test.performance.metadata.FastBulkImportIT
test(org.apache.accumulo.test.performance.metadata.FastBulkImportIT)  Time elapsed: 64.648 sec  <<< FAILURE!
java.lang.AssertionError
        at org.apache.accumulo.test.performance.metadata.FastBulkImportIT.test(FastBulkImportIT.java:109)

The test is checking that the bulk import completes in less than 30 seconds with 5 assignment/process threads, no compactions, and no WAL. That number seems arbitrary, and dependent on many conditions which the test cannot control for. A hard-coded expectation of less than 30 seconds seems unreasonable to me.

Is there a better way we can test that the TServer doesn't re-read bulk-loaded flags, perhaps with a mocked unit test?
