Change subject: avoid opening tablets on failed disks ...................................................................... avoid opening tablets on failed disks Currently Kudu servers can start up with failed disks. However, the moment tablets attempt to bootstrap (i.e. open blocks, etc.), they will attempt to read from the failed disk and fail. This can be avoided by checking whether a tablet's disk group contains a failed disk before attempting to open the tablet. If so, the tablet should be marked as having an error so it can be reassigned. The default behavior of the 'fs_target_data_dirs_per_tablet' flag is updated to take into account disk state when assigning new directory groups. This allows the tablet to be reassigned to a server without being spread across a failed directory. Testing is done by loading data into a cluster with multi-disk servers, failing a single directory of one of the servers, and ensuring that the tablets spread across the failed disk get replicated upon the next startup.
