FileNotFoundException
------------------------------------------------------------------------------------
Key: HBASE-4754
URL: https://issues.apache.org/jira/browse/HBASE-4754
Project: HBase
Issue Type: Bug
Reporter: Ted Yu
Assignee: Ted Yu
Fix For: 0.92.0
As reported by Roman in the thread entitled 'HBase 0.92/Hadoop 0.22 test
results', table creation would result in the following if hadoop 0.22 is the
underlying platform:
{code}
11/11/05 19:08:48 INFO handler.CreateTableHandler: Attemping to create
the table b
11/11/05 19:08:48 ERROR handler.CreateTableHandler: Error trying to
create the table b
java.io.FileNotFoundException: File
hdfs://ip-10-110-254-200.ec2.internal:17020/hbase/b does not exist.

{code}
This was due to how DistributedFileSystem.listStatus() in 0.22 handles
non-existent directory:
{code}
@Override
public FileStatus[] listStatus(Path p) throws IOException {
String src = getPathName(p);
// fetch the first batch of entries in the directory
DirectoryListing thisListing = dfs.listPaths(
src, HdfsFileStatus.EMPTY_NAME);
if (thisListing == null) { // the directory does not exist
throw new FileNotFoundException("File " + p + " does not exist.");
}
{code}
So in FSTableDescriptors.getTableInfoPath(), we should catch
FileNotFoundException and treat it the same way as status being null.
