openinx opened a new issue #2384:
URL: https://github.com/apache/iceberg/issues/2384
I encountered several failures when running the
TestFlinkTableSink#testHashDistributeMode, I think it worth to take some time
to dig what's reason that causing this UT to be flaky.
```java
org.apache.iceberg.flink.TestFlinkTableSink >
testHashDistributeMode[catalogName=testhadoop_basenamespace,
baseNamespace=l0.l1, format=AVRO, isStreaming=true] FAILED
java.lang.AssertionError: There should be only 1 data file in partition
'aaa' expected:<1> but was:<2>
