Change subject: [tools] KUDU-3337 Add unsafe_create_cmeta tool ...................................................................... [tools] KUDU-3337 Add unsafe_create_cmeta tool We've seen some cases when a power outage on XFS lead to empty cmeta files, causing some tablets to fail to start (KUDU-2195). There is a flag to force fsync, but it's disabled by default except for XFS. Fortunately, it's possible to reconstruct how a cmeta should look like based on the information found in ksck (peers) and WAL dumps (term and config index). Still, the only way to actually create a cmeta file even if this information is available, was to copy an existing cmeta file and run "kudu pbc edit" on it, which is very error-prone and hard to automate. This commit introduces a new unsafe_create_cmeta tool under local_replica, which creates a new cmeta file based on the term, config index and peers as provided in CLI arguments. I manually tested this tool by using it to recover a tablet with three empty cmeta files.
