Hello Kudu Jenkins, I'd like you to reexamine a change. Please visit
http://gerrit.cloudera.org:8080/7766 to look at the new patch set (#4). Change subject: disk failure: don't open tablets on failed disks ...................................................................... disk failure: don't open tablets on failed disks Currently Kudu servers open the FS layout 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 read data from 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 configured to use multiple directories for data blocks, failing a single directory on one of the tablet servers, and ensuring that the tablets with blocks on the failed directory get re-replicated at startup time.
