安裝 (需要 Java )
| yum -y install java export JAVA_HOME=/usr/lib/jvm/java-1.7.0-openjdk-1.7.0.91-2.6.2.3.el7.x86_64/jre
echo 'export JAVA_HOME=/usr/lib/jvm/java-1.7.0-openjdk-1.7.0.91-2.6.2.3.el7.x86_64/jre' >> /etc/profile
echo 'export PATH=$PATH:$JAVA_HOME/bin' >> /etc/profile
echo 'export CLASSPATH=$JAVA_HOME/jre/lib/ext:$JAVA_HOME/lib/tools.jar' >> /etc/profile
source /etc/profile
java -version |
JAVA_HOME 路徑選擇可參考選結尾 /bin/java 的
(不要選 /usr/bin/java，有些功能操作下會出問題)

help說明
hbase(main):001:0> help
HBase Shell, version 1.2.1, r8d8a7107dc4ccbf36a92f64675dc60392f85c015, Wed Mar 30 11:19:21 CDT 2016
Type 'help "COMMAND"', (e.g. 'help "get"' -- the quotes are necessary) for help on a specific command. Commands are grouped. Type 'help "COMMAND_GROUP"', (e.g. 'help "general"') for help on a command group. COMMAND GROUPS: Group name: general Commands: status, table_help, version, whoami Group name: ddl Commands: alter, alter_async, alter_status, create, describe, disable, disable_all, drop, drop_all, enable, enable_all, exists, get_table, is_disabled, is_enabled, list, locate_region, show_filters Group name: namespace Commands: alter_namespace, create_namespace, describe_namespace, drop_namespace, list_namespace, list_namespace_tables Group name: dml Commands: append, count, delete, deleteall, get, get_counter, get_splits, incr, put, scan, truncate, truncate_preserve Group name: tools Commands: assign, balance_switch, balancer, balancer_enabled, catalogjanitor_enabled, catalogjanitor_run, catalogjanitor_switch, close_region, compact, compact_rs, flush, major_compact, merge_region, move, normalize, normalizer_enabled, normalizer_switch, split, trace, unassign, wal_roll, zk_dump Group name: replication Commands: add_peer, append_peer_tableCFs, disable_peer, disable_table_replication, enable_peer, enable_table_replication, list_peers, list_replicated_tables, remove_peer, remove_peer_tableCFs, set_peer_tableCFs, show_peer_tableCFs Group name: snapshots Commands: clone_snapshot, delete_all_snapshot, delete_snapshot, list_snapshots, restore_snapshot, snapshot Group name: configuration Commands: update_all_config, update_config Group name: quotas Commands: list_quotas, set_quota Group name: security Commands: grant, list_security_capabilities, revoke, user_permission Group name: procedures Commands: abort_procedure, list_procedures Group name: visibility labels Commands: add_labels, clear_auths, get_auths, list_labels, set_auths, set_visibility SHELL USAGE: Quote all names in HBase Shell such as table and column names. Commas delimit command parameters. Type <RETURN> after entering a command to run it. Dictionaries of configuration used in the creation and alteration of tables are Ruby Hashes. They look like this: {'key1' => 'value1', 'key2' => 'value2', ...} and are opened and closed with curley-braces. Key/values are delimited by the '=>' character combination. Usually keys are predefined constants such as NAME, VERSIONS, COMPRESSION, etc. Constants do not need to be quoted. Type 'Object.constants' to see a (messy) list of all constants in the environment. If you are using binary keys or values and need to enter them in the shell, use double-quote'd hexadecimal representation. For example: hbase> get 't1', "key\x03\x3f\xcd" hbase> get 't1', "key\003\023\011" hbase> put 't1', "test\xef\xff", 'f1:', "\x01\x33\x40" The HBase shell is the (J)Ruby IRB with the above HBase-specific commands added. For more on the HBase Shell, see http://hbase.apache.org/book.html hbase(main):002:0> |
建立稱為 mytable 的資料表，和稱為 mycolumnfamily 的 column family。
hbase(main):002:0> create "mytable", "mycolumnfamily"
0 row(s) in 0.4600 seconds => Hbase::Table - mytable hbase(main):003:0> |
檢視 mytable 資訊
hbase(main):003:0> describe "mytable" Table mytable is ENABLED mytable COLUMN FAMILIES DESCRIPTION {NAME => 'mycolumnfamily', DATA_BLOCK_ENCODING => 'NONE', BLOOMFILTER => 'ROW', REPLICATION_SCOPE => '0', VERSIONS => '1', COMPRESSION => 'NONE', MIN_VERSIONS = > '0', TTL => 'FOREVER', KEEP_DELETED_CELLS => 'FALSE', BLOCKSIZE => '65536', IN _MEMORY => 'false', BLOCKCACHE => 'true'} 1 row(s) in 0.0310 seconds hbase(main):004:0> |
增加一列 myrow 到 "mycolumnfamily:x" 行，值為 v
hbase(main):004:0> put "mytable", "myrow", "mycolumnfamily:x", "v" 0 row(s) in 0.0740 seconds hbase(main):005:0> |
顯示值
hbase(main):005:0> get "mytable", "myrow" COLUMN CELL mycolumnfamily:x timestamp=1462345842547, value=v 1 row(s) in 0.0680 seconds |
掃描 mytable
hbase(main):006:0> scan "mytable" ROW COLUMN+CELL myrow column=mycolumnfamily:x, timestamp=1462345842547, value=v 1 row(s) in 0.0510 seconds |
離開交談模式
| hbase(main):007:0> quit |
停止 hbase
| [root@localhost ~]# $HBASE_HOME/bin/stop-hbase.sh stopping hbase............. |
