Matteo Bertozzi commented on HBASE-10622:
-----------------------------------------
{quote}In the run(), can we cleanup/delete snapshotTmpDir if Step 2 failed so
that we don't ask the user to manually clean it since it comes from our Step 1
copy?{quote}
There is an -overwrite option that does already this, but I think the general
problem should be solved by the last line of this patch where the
snapshotTmpDir is removed if you get an exception.
{quote}Another issue is probably more involved, and does not need to be covered
in this JIRA. It is the overall progress reporting of the ExportSnapshot
job.{quote}
other jira, it requires a new InputFormat/RecordReader with the progress based
on the file size and not on the number of lines in the input file. The only
progress that we track is the current file copy
