-------------------------------------
Summary: ITestS3ABlockOutputArray failure with IO File name too
long
Key: HADOOP-18744
URL: https://issues.apache.org/jira/browse/HADOOP-18744
Project: Hadoop Common
Issue Type: Sub-task
Components: fs/s3
Reporter: Ahmar Suhail
On an EC2 instance, the following tests are failing:
{{{}ITestS3ABlockOutputArray.testDiskBlockCreate{}}}{{{}ITestS3ABlockOutputByteBuffer>ITestS3ABlockOutputArray.testDiskBlockCreate{}}}{{{}ITestS3ABlockOutputDisk>ITestS3ABlockOutputArray.testDiskBlockCreate{}}}
with the error IO File name too long.
The tests create a file with a 1024 char file name and rely on
File.createTempFile() to truncate the file name to < OS limit.
