Konstantin Boudnik commented on HDFS-728: ----------------------------------------- Merging together last two comments and adding some thoughts on top: - no split of the test case is required then. So, my patch could be modified slightly and seems to be good to go. - this is clearly a functional test, so it make sense to create a separate directory structure like {{test/src/functional}} - for this new target a different timeout settings would be required > Creat a comprehensive functional test for append > ------------------------------------------------ > > Key: HDFS-728 > URL: https://issues.apache.org/jira/browse/HDFS-728 > Project: Hadoop HDFS > Issue Type: New Feature > Affects Versions: 0.21.0 > Reporter: Hairong Kuang > Assignee: Hairong Kuang > Fix For: 0.21.0 > > Attachments: appendTest.patch, HDFS-728.patch > > > This test aims to do > 1. create a file of len1; > 2. reopen the file for append; > 3. write len2 bytes to the file and hflush; > 4. write len3 bytes to the file and close the file; > 5. validate the content of the file. > Len1 ranges from [0, 2*BLOCK_SIZE+1], len2 ranges from [0, BLOCK_SIZE+1], and > len3 ranges from [0, BLOCK_SIZE+1]. The test tries all combination of len1, > len2, and len3. To minimize the running time, bytes per checksum is set to be > 4 bytes, each packet size is set to be bytes per checksum, and each block > contains 2 packets. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
