URL: https://github.com/apache/hadoop/pull/4382
JIRA: HDFS-16609. Fix Flakes Junit Tests that often report timeouts.
When I was dealing with
[HDFS-16590](https://issues.apache.org/jira/browse/HDFS-16590) JIRA, Junit
Tests often reported errors, I found that one type of problem is TimeOut
problem, these problems can be avoided by adjusting TimeOut time.
The modified method is as follows:
1.org.apache.hadoop.hdfs.TestFileCreation#testServerDefaultsWithMinimalCaching
```
[ERROR]
testServerDefaultsWithMinimalCaching(org.apache.hadoop.hdfs.TestFileCreation)
Time elapsed: 7.136 s <<< ERROR!
