----------------------------------
Summary: [HBCK2] addFsRegionsMissingInMeta command should support
dumping region list into a file which can be passed as input to assigns command
Key: HBASE-27724
URL: https://issues.apache.org/jira/browse/HBASE-27724
Project: HBase
Issue Type: Improvement
Components: hbase-operator-tools, hbck2
Reporter: Nihal Jain
Assignee: Nihal Jain
_addFsRegionsMissingInMeta_ command currently outputs a command as last line of
output which needs to be run with hbck2
{code:java}

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 -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}
