Ted Yu created FLINK-3773:
-----------------------------
Summary: Scanners are left unclosed in SqlExplainTest
Key: FLINK-3773
URL: https://issues.apache.org/jira/browse/FLINK-3773
Project: Flink
Issue Type: Bug
Reporter: Ted Yu
Priority: Minor
e.g.
{code}
String source = new Scanner(new File(testFilePath +
"../../src/test/scala/resources/testFilter0.out"))
{code}
Scanner implements AutoCloseable.
Using try-with-resources would be a good pattern for closing the Scanners.
