4 -a,--checkfamily Enable family check
5 -b,--printblocks Print block index meta data
6 -e,--printkey Print keys
7 -f,--file File to scan. Pass full-path; e.g.
8 hdfs://a:9000/hbase/hbase:meta/12/34
9 -k,--checkrow Enable row order check; looks for out-of-order
10 keys
11 -m,--printmeta Print meta data of file
12 -p,--printkv Print key/value pairs
13 -r,--region Region to scan. Pass region name; e.g.
14 'hbase:meta,,1'
15 -s,--stats Print statistics
16 -v,--verbose Verbose output; emits file and meta data
17 delimiters
18 -w,--seekToRow Seek to this row and print all the kvs for this
