Parquet backed table corrupted - HIVE - expected magic number at tail [80, 65, 82, 49] but found [1, 92, 78, 10] - hive

Question

Distribution: CDH-4.6.0-1.cdh4.6.0.p0.26
Hive Version: 0.10.0
Parquet Version: 1.2.5
I have two big date partitioned external Hive tables full of log files that I recently converted to Parquet to take advantage of the compression and columnar storage. So far I've been very happy with the performance.
Our dev team recently added a field to the logs, so I was charged with adding a column to both log tables. It worked perfectly for one, but the other appears to have become corrupted. I reverted the change, but I still can't query the table.
I'm convinced the data is fine (because it didn't change) but something is wrong in the metastore. An msck repair table repopulates the partitions after I drop/create, but does not take care of the error below. There are two things that can fix it, but neither are making me happy:
Re-insert the data.
Copy data back into the table from the production cluster.
I'm really hoping there's a command that I don't know about that will fix the table without needing to resort to the above 2 options. Like I said, the data is fine. I've googled the heck out of the error, and I get some results but they all pertain to Impala which is NOT what were using.
select * from upload_metrics_hist where dt = '2014-07-01' limit 5;
The problem is this:
Caused by: java.lang.RuntimeException: hdfs://hdfs-dev/data/prod/upload-metrics/upload_metrics_hist/dt=2014-07-01/000005_0 is not a Parquet file. expected magic number at tail [80, 65, 82, 49] but found [1, 92, 78, 10]
