Thank you @dombizita for the patch.
It does indeed look like the header has 12 columns while this one only has 1.
The last addition of a column was 2 years ago in HDFS-16203.
I wonder if there is a way we can prevent this in the future.
@ferhui @tasanuma @tomscut worked in that fix.
Can you confirm that this is OK?
