Walter Su created HDFS-8607:
-------------------------------
Summary: TestFileCorruption doesn't work as expected
Key: HDFS-8607
URL: https://issues.apache.org/jira/browse/HDFS-8607
Project: Hadoop HDFS
Issue Type: Bug
Reporter: Walter Su
Assignee: Walter Su
Although it passes, it's useless.
{code}
77 File[] blocks = data_dir.listFiles();
78 assertTrue("Blocks do not exist in data-dir", (blocks != null) &&
(blocks.length > 0));
79 for (int idx = 0; idx < blocks.length; idx++) {
80 if (!blocks[idx].getName().startsWith(Block.BLOCK_FILE_PREFIX)) {
81 continue;
82 }
83 System.out.println("Deliberately removing file "+blocks[idx].getName());
84 assertTrue("Cannot remove file.", blocks[idx].delete());
85 }
{code}
blocks are located at finalized/subdir0/subdir0, but line 77 only returns
"subdir0" because {{File.listFiles()}} is not recursive. So line 83~84 will
never be excuted.
