> NegativeArraySizeException thrown in FSOutputSummer.java given large

> Key: HADOOP-18896
> URL: https://issues.apache.org/jira/browse/HADOOP-18896
> Project: Hadoop Common
> Issue Type: Bug
> Affects Versions: 3.3.6
> Reporter: rstest
> Priority: Critical
> Labels: pull-request-available
>
> Buffer size of FSOutputSummer equals to `file.bytes-per-checksum` times
> `BUFFER_NUM_CHUNKS`. A large `file.bytes-per-checksum` causes buffer size to
> overflow and crash with NegativeArraySizeException.
> To reproduce:
> 1. set `file.bytes-per-checksum` to 238609295
> 2. `mvn surefire:test
> -Dtest=org.apache.hadoop.hdfs.TestDecommissionWithStriped#testFileSmallerThanOneStripe`
> We created a PR that provides a fix which checks the buffer size is positive
> after multiplying `file.bytes-per-checksum` with `BUFFER_NUM_CHUNKS`
