Andor Molnar created HBASE-28254: ------------------------------------ Summary: Flaky test: TestTableShell Key: HBASE-28254 URL: https://issues.apache.org/jira/browse/HBASE-28254 Project: HBase Issue Type: Test Components: flakies, integration tests Reporter: Andor Molnar Assignee: Andor Molnar
The test is running the following Ruby commands: {noformat} # Instert test data @test_table.put(1, "x:a", 1) @test_table.put(2, "x:raw1", 11) @test_table.put(2, "x:raw1", 11) @test_table.put(2, "x:raw1", 11) @test_table.put(2, "x:raw1", 11) {noformat} And validate the versions with: {noformat} args = { VERSIONS => 10, RAW => true } # Since 4 versions of row with rowkey 2 is been added, we can use any number >= 4 for VERSIONS to scan all 4 versions. num_rows = 0 @test_table._scan_internal(args) do # Raw Scan num_rows += 1 end # 5 since , 1 from row key '1' and other 4 from row key '4' assert_equal(num_rows, 5, 'Num rows scanned without RAW/VERSIONS are not 5') {noformat} Which sometimes (almost always on fast machines) fails, because it only finds 3 versions out of 4. I believe this due to commands are running too fast and inserts data with same timestamp, so HBase cannot distinguish them. I'd like to add some sleep between puts to fix it. -- This message was sent by Atlassian Jira (v8.20.10#820010)
