HBASE基础命令总结一，概述 本文中介绍了hbase的基础命令，作者既有记录总结hbase基础命令的目的还有本着分享的精神，和广大读者一起进步。本文的hbase版本是：HBase 1.2.0-cdh5.10.0。 二，HBase工具命令
上面的 master、regionserver、zookeeper、rest、thrift、thrift2 都是启动命令启动命令就不介绍了。下面一一介绍我认为比较重要的命令： 1，hbase shell 命令这个命令主要是进入hbase客户端client 的命令，在这里可以操作hbase 数据库，诸如：增删改查等这个命令内容较多，本文简单介绍这个命令以后会着重讲解这个命令见下面代码： hbase(main):001:0> help HBase Shell, version 1.2.0-cdh5.10.0, rUnknown, Fri Jan 20 12:13:18 PST 2017 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_mob, compact_rs, flush, major_compact, major_compact_mob, 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, get_peer_config, list_peer_configs, list_peers, list_replicated_tables, remove_peer, remove_peer_tableCFs, set_peer_tableCFs, show_peer_tableCFs, update_peer_config 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 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.html2，hbase hbck 检测命令

这是一个用于检查区域一致性和表完整性问题并且修复损坏的Hbase的工具，它工作在两种基本模式-只读不一致识别模式和多阶段写修复模式。如果想要检查您的hbase集群是否损坏就运行命令 hbase hbck hbase hbck ：此处的命令有很多INFO日志，本文已经略去 在命令结束的时候，它会打印OK或者告诉您存在的INCONSISTENCIES数量。偶尔的不一致也可能是暂时的所以要多运行几次。 Java HotSpot(TM) 64-Bit Server VM warning: Using incremental CMS is deprecated and will likely be removed in a future release 19/03/03 10:51:44 INFO Configuration.deprecation: fs.default.name is deprecated.

如果信息过多还可以针对表来进行检测比如： hbase hbck test test 就是表名 3，hbase hbck 修复命令 如果多次检测都出现了不一致或者其他问题，那么就要针对性的修复了修复命令如： hbase hbck -fixVersionFile 解决缺失hbase.version 文件 的问题 hbase hbck -fixAssignments 解决 用于修复region没有assign、不应该assign、assign多次的问题。 如果region既不在meta表中，又不在hdfs上，但是在regionserver的online region集合中； 如果一个region在META表中有记录，在hdfs上面也有，table不是disabled的，但是这个region没有被服务； 如果一个region在META表中有记录，在hdfs上面也有，table是disabled的，但是这个region被某个regionserver服务了； 如果一个region在META表中有记录，在hdfs上面也有，table不是disabled的，但是这个region被多个regionserver服务了； 如果一个region在META表中，在hdfs上面也有，也应该被服务，但是META表中记录的regionserver和实际所在的regionserver不相符 hbase hbck -fixAssignments -fixMeta 解决如果一个region在meta中，并且在regionserver的online region集合中，但是hdfs集合没有，（-fixAssignments告诉regionserver close region），（-fixMeta删除META表中region的记录） hbase hbck -fixMeta -fixAssignments 解决 如果一个region在meta表中没有记录，没有被regionserver服务，但是hdfs上面有。（-fixAssignments 用于assign region），（ -fixMeta用于在META表中添加region的记录） hbase hbck -fixMeta 解决如果hdfs上面没有，那么从Meta表中删除相应的记录，如果hdfs上面有，在meta表中添加相应的记录。 如果一个region在Meta表中没有记录，在hdfs上面有，被regionserver服务了；如果在meta有记录，但是在hdfs没有，并且没有被regionserver服务；
hbase hbck -fixHdfsHoles 创建一个新的空region，填补空洞，但是不assign 这个 region，也不在META表中添加这个region的相关信息, 选项只是创建了一个新的空region，填补上了这个区间，还需要加上-fixAssignments -fixMeta 来解决问题， -fixAssignments 用于assign region， -fixMeta用于在META表中添加region的记录， 所以有了组合拳 -repairHoles 修复region holes，相当于-fixAssignments -fixMeta -fixHdfsHoles -fixHdfsOrphans hbase hbck -fixHdfsOrphans region在hdfs上面没有.regioninfo文件 hbase hbck -fixHdfsOverlaps hbase hbck -repair 这个命令是打开所有的修复项目，相当于 -fixAssignments -fixMeta -fixHdfsHoles -fixHdfsOrphans -fixHdfsOverlaps -fixVersionFile -sidelineBigOverlaps 4，hbase snapshot 命令 使用这个命令可以创建hbase快照：
举例说明：hbase snapshot -name test_snapshot -table test 这个命令就是给表test创建一个快照快照名字叫做 test_snapshot 5，hbase snapshotinfo 命令 这是查看hbase 快照信息的
举例说明：hbase snapshotinfo -snapshot test1 -files
6，hbase wal 命令
