crashes with NegativeArraySizeException during initialization
URL: https://github.com/apache/hadoop/pull/6065
> GcTimeMonitor crashes with NegativeArraySizeException during initialization
> ---------------------------------------------------------------------------
>
> Key: HDFS-17189
> URL: https://issues.apache.org/jira/browse/HDFS-17189
> Project: Hadoop HDFS
> Issue Type: Bug
> Affects Versions: 3.3.6
> Reporter: ConfX
> Priority: Major
> Labels: pull-request-available
>
> The garbage collection data buffer size equals to
> `dfs.namenode.gc.time.monitor.observation.window.ms` divided by
> `dfs.namenode.gc.time.monitor.sleep.interval.ms` plus 2. When the observation
> window is a large value, the caculation overflows, resulting in a negative
> buffer size.
> To reproduce:
> 1. set `dfs.namenode.gc.time.monitor.observation.window.ms` to 945099495m
> 2. run `mvn surefire:test
> -Dtest=org.apache.hadoop.hdfs.TestHDFSFileSystemContract#testWriteReadAndDeleteHalfABlock`
> We create a PR that provides a fix by checking the computed buffer size is
> not only within `128 * 1024` but also greater than 0.
