Description

Running the following line, using /bin/sh:

$ bin/local-regionservers.sh --config ~/hbase-dev/hbase-conf/conf/ start 1 2 3 4 5

Produces the output below:

bin/local-regionservers.sh: 55: bin/local-regionservers.sh: [[: not found
Invalid argument
bin/local-regionservers.sh: 55: bin/local-regionservers.sh: [[: not found
Invalid argument
bin/local-regionservers.sh: 55: bin/local-regionservers.sh: [[: not found
Invalid argument
bin/local-regionservers.sh: 55: bin/local-regionservers.sh: [[: not found
Invalid argument
bin/local-regionservers.sh: 55: bin/local-regionservers.sh: [[: not found
Invalid argument

Considering:

if [[ "$i" =~ ^[0-9]+$ ]]; then
   run_master $cmd $i
  else
   echo "Invalid argument"
fi

The reasons is that the regex operator =~ doesn't have compatibility with /bin/sh but works running /bin/bash

$ bash -x bin/local-regionservers.sh --config ~/hbase-dev/hbase-conf/conf/ start 1 2 3 4 5
