## What changes were proposed in this pull request? This PR proposes to fix lint-check failures and javadoc8 break. Few errors were introduced as below: **lint-check failures** ``` [ERROR] src/test/java/org/apache/spark/network/TransportClientFactorySuite.java:[45,1] (imports) RedundantImport: Duplicate import to line 43 - org.apache.spark.network.util.MapConfigProvider. [ERROR] src/main/java/org/apache/spark/unsafe/types/CalendarInterval.java:[255,10] (modifier) RedundantModifier: Redundant 'final' modifier. ``` **javadoc8** ``` [error] .../spark/sql/core/target/java/org/apache/spark/sql/streaming/StreamingQueryProgress.java:19: error: bad use of '>' [error] * "max" -> "2016-12-05T20:54:20.827Z" // maximum event time seen in this trigger [error] ^ [error] .../spark/sql/core/target/java/org/apache/spark/sql/streaming/StreamingQueryProgress.java:20: error: bad use of '>' [error] * "min" -> "2016-12-05T20:54:20.827Z" // minimum event time seen in this trigger [error] ^ [error] .../spark/sql/core/target/java/org/apache/spark/sql/streaming/StreamingQueryProgress.java:21: error: bad use of '>' [error] * "avg" -> "2016-12-05T20:54:20.827Z" // average event time seen in this trigger [error] ^ [error] .../spark/sql/core/target/java/org/apache/spark/sql/streaming/StreamingQueryProgress.java:22: error: bad use of '>' [error] * "watermark" -> "2016-12-05T20:54:20.827Z" // watermark used in this trigger [error] ``` ## How was this patch tested? Manually checked as below: **lint-check failures** ``` ./dev/lint-java Checkstyle checks passed. ``` **javadoc8** This seems hidden in the API doc but I manually checked after removing access modifier as below: It looks not rendering properly (scaladoc).  After this PR, it renders as below: - scaladoc  - javadoc  Author: hyukjinkwon <gurwls223@gmail.com> Closes #16307 from HyukjinKwon/lint-javadoc8. |
