> At first, TruncateTableProcedure failed to write some files to HDFS in
> TRUNCATE_TABLE_CREATE_FS_LAYOUT state for some reason.

> procedure.TruncateTableProcedure: Retriable error trying to truncate
> table=<namespace>:<table> state=TRUNCATE_TABLE_CREATE_FS_LAYOUT

> But at this time, seemed like writing some files to HDFS was successful.
> And then, TruncateTableProcedure was stuck in retry loop in
> TRUNCATE_TABLE_CREATE_FS_LAYOUT state. At this point, the following log
> messages were shown repeatedly in the master log:
> {code:java}
> 2018-05-15 08:00:25,463 WARN [ProcedureExecutorThread-8]
> procedure.TruncateTableProcedure: Retriable error trying to truncate
> table=<namespace>:<table> state=TRUNCATE_TABLE_CREATE_FS_LAYOUT
> java.io.IOException: java.util.concurrent.ExecutionException:
> java.io.IOException: The specified region already exists on disk:
> hdfs://<name>/apps/hbase/data/.tmp/data/<namespace>/<table>/<region>
> ...
> {code}
> It seems like this is because TruncateTableProcedure tried to write the files
> that were written successfully in the first try.
> I think we need to delete all the files and directories that are written
> successfully in the previous try before retrying the
> TRUNCATE_TABLE_CREATE_FS_LAYOUT state.
> Actually, this issue was observed in HDP-2.5.3, but I think the upstream has
> the same issue. Also, it looks to me that CreateTableProcedure has a similar
> issue.
