--------------------------------

             Summary: list_labels shell command should return readable labels
                 Key: HBASE-30283
                 URL: https://issues.apache.org/jira/browse/HBASE-30283
             Project: HBase
          Issue Type: Improvement
          Components: shell
            Reporter: Xiao Liu
            Assignee: Xiao Liu
             Fix For: 3.0.0, 2.7.0, 2.5.16, 2.6.7


Running {{list\_labels}} in the hbase shell echoes the raw protobuf return
value, e.g.:

{code:language=bash|borderStyle=solid|theme=RDark|linenumbers=true|collapse=false}
hbase:004:0> list_labels
A
B
Took 0.0105 seconds
=> #<Java::OrgApacheHbaseThirdpartyComGoogleProtobuf::ProtobufArrayList: 
[#<Java::OrgApacheHbaseThirdpartyComGoogleProtobuf::ByteString::LiteralByteString:0x4204c372>,
 
#<Java::OrgApacheHbaseThirdpartyComGoogleProtobuf::ByteString::LiteralByteString:0x13eb7283>]>
{code}

Found while working on HBASE-30266, with this patch:

{code:language=bash|borderStyle=solid|theme=RDark|linenumbers=true|collapse=false}
hbase:001:0> list_labels
A
B
Took 0.4680 seconds
=> ["A", "B"]
{code}
