> Lower the default maximum number of blocks per file

> We introduced the maximum number of blocks per file in HDFS-4305, but we set
> the default to 1MM. In practice this limit is so high as to never be hit,
> whereas we know that an individual file with 10s of thousands of blocks can
> cause problems. We should lower the default value, in my opinion to 10k.
