Andrew Wang updated HDFS-3924:
------------------------------
Attachment: hdfs-3924-1.patch
Patch changing the {{byte}} to an {{int}}, which should be sufficient for any
realistic number of disks per machine. Also fixed a typo.
I didn't manually test with >127 storage locations, but I ran the existing
BlockStorage tests (which passed), and the ids printed in the output looked
sane.
> Multi-byte id in HdfsVolumeId

> Currently, the {{id}} in {{HdfsVolumeId}} is just a single byte. It'd be nice
> to make this larger, for situations where there's more than 255 disks.
