Boris Osipov created FLINK-5077: ----------------------------------- Summary: testStreamTableSink falls unstable Key: FLINK-5077 URL: https://issues.apache.org/jira/browse/FLINK-5077 Project: Flink Issue Type: Bug Components: Table API & SQL Affects Versions: 1.1.4 Reporter: Boris Osipov
I've faced with several fails TableSinkITCase.testStreamTableSink test. {code} Tests run: 1, Failures: 1, Errors: 0, Skipped: 0, Time elapsed: 16.938 sec <<< FAILURE! - in org.apache.flink.api.scala.stream.TableSinkITCase testStreamTableSink(org.apache.flink.api.scala.stream.TableSinkITCase) Time elapsed: 10.534 sec <<< FAILURE! java.lang.AssertionError: Different number of lines in expected and obtained result. expected:<8> but was:<4> at org.junit.Assert.fail(Assert.java:88) at org.junit.Assert.failNotEquals(Assert.java:834) at org.junit.Assert.assertEquals(Assert.java:645) at org.apache.flink.test.util.TestBaseUtils.compareResultsByLinesInMemory(TestBaseUtils.java:316) at org.apache.flink.test.util.TestBaseUtils.compareResultsByLinesInMemory(TestBaseUtils.java:302) at org.apache.flink.api.scala.stream.TableSinkITCase.testStreamTableSink(TableSinkITCase.scala:61) {code} I made small research. I added additional StreamITCase.StringSink {code} val results = input.toTable(tEnv, 'a, 'b, 'c) .where('a < 5 || 'a > 17) .select('c, 'b) results.writeToSink(new CsvTableSink(path)) results.toDataStream[Row] .addSink(new StreamITCase.StringSink) {code} and logging. I've ran test several times and I got following resuts in log on fail: {noformat} ---------- Actual CsvTableSink: Comment#13,6 Comment#14,6 Comment#15,6 Hello world, how are you?,3 Hello world,2 Hi,1 ---------- Stream sink: Comment#12,6 Comment#13,6 Comment#14,6 Comment#15,6 Hello world, how are you?,3 Hello world,2 Hello,2 Hi,1 ---------- Expected result: Comment#12,6 Comment#13,6 Comment#14,6 Comment#15,6 Hello world, how are you?,3 Hello world,2 Hello,2 Hi,1 {noformat} Looks like writing to cvs works wrong. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
