Block CRC Unit Tests: upgrade test
----------------------------------
Key: HADOOP-1629
URL: https://issues.apache.org/jira/browse/HADOOP-1629
Project: Hadoop
Issue Type: Test
Components: dfs
Affects Versions: 0.14.0
Reporter: Nigel Daley
Priority: Blocker
Fix For: 0.14.0
HADOOP-1286 introduced a distributed upgrade framework. 1 or more unit tests
should be developed that start with a zipped up Hadoop 0.12 file system (that
is included in Hadoop's src/test directory under version controlled) and
attempts to upgrade it to the current version of Hadoop (ie the version that
the tests are running against). The zipped up file system should include some
"interesting" files, such as:
- zero length files
- file with replication set higher than number of datanodes
- file with no .crc file
- file with corrupt .crc file
- file with multiple blocks (will need to set dfs.block.size to a small value)
- file with multiple checksum blocks
- empty directory
- all of the above again but with a different io.bytes.per.checksum setting
The class that generates the zipped up file system should also be included in
this patch.
