$ ./bin/hbase shell

Type help and then <RETURN> to see a listing of shell commands and options. Browse at least the paragraphs at the end of the help output for the gist of how variables and command arguments are entered into the HBase shell; in particular note how table names, rows, and columns, etc., must be quoted.

See shell exercises for example basic shell operation.

Here is a nicely formatted listing of all shell commands by Rajeshbabu Chintaguntla.

2、脚本使用

Running the Shell in Non-Interactive Mode

To invoke non-interactive mode, pass the -n or --non-interactive option to HBase Shell.

HBase Shell in OS Scripts

$ echo "describe 'test1'" | ./hbase shell -n

describe 'test1'

To suppress all output, echo it to /dev/null:

$ echo "describe 'test'" | ./hbase shell -n > /dev/null 2>&1
