@HyukjinKwon @dongjoon-hyun I have ignored the test and also disabled the feature by default. |

Instead of this, the following will help us keep our test coverage in Java 8 CI.
SystemUtils.isJavaVersionAtLeast(JavaVersion.JAVA_9)

Oh, I see. So I can keep the test enabled but it would be ignored with assume in JDK 11 and JDK 17?

No, I don't know yet. |

+1, I manually validated that the test cases are ignored correctly.
[info] HiveSerDeReadWriteSuite:
[info] - SPARK-40815: DelegateSymlinkTextInputFormat serialization !!! CANCELED !!! (15 milliseconds)
[info] org.apache.commons.lang3.SystemUtils.isJavaVersionAtLeast(JAVA_9) was true (HiveSerDeReadWriteSuite.scala:232)
...
I'm also digging this issue.

…tInputFormat to avoid Hive ExecMapper.getDone() check ### What changes were proposed in this pull request? Follow-up for #38504. This PR fixes an issue where a unit test for SymlinkTextInputFormat would fail in JDK 11. The fix is to return the record reader directly instead of wrapping it with `HiveRecordReader`. The issue could be reproduced by running a test right before SPARK-40815 tests with JDK 11 and appears to be related to `ExecMapper.getDone()` (https://github.com/apache/hive/blob/branch-2.3/ql/src/java/org/apache/hadoop/hive/ql/io/HiveRecordReader.java#L76). This check is for a static variable that is set when the map job is done to limit results. Note that there is no synchronisation around `getDone()` or `setDone()`, it is just a static mutable variable. Once that is set, the record reader returns 0 records. I don't know why it works in JDK 8 but not in JDK 11 but my current suspicion is something related to class loader in JDK similar to this patch: apache/hive@a234475 (maybe this is the fix but I was not able to verify). ### Why are the changes needed? Re-enables the test and fixes an issue with DelegateSymlinkTextInputFormat returning 0 records. Note that this is still an issue with SymlinkTextInputFormat as this needs to be addressed in Hive. ### Does this PR introduce _any_ user-facing change? No. ### How was this patch tested? I re-enabled the unit tests that used to fail in JDK 11 and extended a test to cover LIMIT. Closes #38544 from sadikovi/fix-symlink-test-2.
