> _addFsRegionsMissingInMeta_ command currently outputs a command as last line of output which needs to be run with hbck2
> {code:java}
> assigns 22d30d9e332af3272302cf780da14c3c 43245731f82e5bb907a4433f688574c1 5a19939f4f219ab177dd5b376dcb882f 774514b1027846c4e3b6702e193ce03d 7f6ad3360e0a4811c4dace8c1a901f40 8cd363e4da1b95fd43166f451546ad63 90e3414947f9500ec01f6672103f29d0{code}
> This is good, but the user has to copy and format the command, which can get really big depending on how many regions need to be assigned.
> _addFsRegionsMissingInMeta_ should support a flag, say -f to facilitate dumping region list into a file, which can be passed onto as input to _assigns_ command via -i parameter.
> Sample expected use-case:
> {code:java}
> # Dump output of command (in a formatted manner) to file
> hbase hbck -j hbase-hbck2-version.jar addFsRegionsMissingInMeta -i table_list.txt -f regions_to_assign.txt
> # Pass file as input to assigns
> hbase hbck -j hbase-hbck2-version.jar assigns -i regions_to_assign.txt{code}
