Ted Yu commented on HBASE-7704:
-------------------------------
In processRegion():
{code}
+ hFileV1Set.add(storeFilePath);
+ // return this region path, as it needs to be compacted.
+ return path;
{code}
There may be more than one V1 HFile in the region, right ? Why do we return
early ?
{code}
+ * Tool to detect presence of any HFileV1 in the given directory. It prints
all such regions which
+ * has such files.
{code}
'has such files' -> 'have such files'
{code}
+ * It also support -h, --help, -help options.
{code}
'support' -> 'supports'
> migration tool that checks presence of HFile V1 files

> Below was Stack's comment from HBASE-7660:
> Regards the migration 'tool', or 'tool' to check for presence of v1 files, I
> imagine it as an addition to the hfile tool
> http://hbase.apache.org/book.html#hfile_tool2 The hfile tool already takes a
> bunch of args including printing out meta. We could add an option to print
> out version only – or return 1 if version 1 or some such – and then do a bit
> of code to just list all hfiles and run this script against each. Could MR it
> if too many files.
