["stack (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/HBASE-21210?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

stack resolved HBASE-21210.
---------------------------
      Resolution: Fixed
    Release Note: 
Added a bypass to hbck2:

{code}
$ HBASE_CLASSPATH_PREFIX=../hbase-operator-tools/hbase-hbck2/target/hbase-hbck2-1.0.0-SNAPSHOT.jar ./bin/hbase org.apache.hbase.HBCK2
usage: HBCK2 [OPTIONS] COMMAND <ARGS>

Options:
 -d,--debug                                 run with debug output
 -h,--help                                  output this help message
 -p,--hbase.zookeeper.property.clientPort   peerport of target hbase
                                            ensemble
 -q,--hbase.zookeeper.quorum <arg>          ensemble of target hbase
 -z,--zookeeper.znode.parent                parent znode of target hbase

Commands:
 setTableState <TABLENAME> <STATE>
   Possible table states: ENABLED, DISABLED, DISABLING, ENABLING
   To read current table state, in the hbase shell run:
     hbase> get 'hbase:meta', '<TABLENAME>', 'table:state'
   A value of \x08\x00 == ENABLED, \x08\x01 == DISABLED, etc.
   An example making table name 'user' ENABLED:
     $ HBCK2 setTableState users ENABLED
   Returns whatever the previous table state was.

 assigns <ENCODED_REGIONNAME>...
   A 'raw' assign that can be used even during Master initialization.
   Skirts Coprocessors. Pass one or more encoded RegionNames:
   e.g. 1588230740 is hard-coded encoding for hbase:meta region and
   de00010733901a05f5a2a3a382e27dd4 is an example of what a random
   user-space encoded Region name looks like. For example:
     $ HBCK2 assign 1588230740 de00010733901a05f5a2a3a382e27dd4
   Returns the pid of the created AssignProcedure or -1 if none.

 bypass [OPTIONS] <PID>...
   Pass one (or more) procedure 'pid's to skip to the procedure finish.
   Parent of this procedures will also skip to its finish. Entities will
   be left in an inconsistent state and will require manual fixup.
   Pass --force to break any outstanding locks.
   Pass --waitTime=<seconds> to wait on entity lock before giving up.
   Default: force=false and waitTime=0. Returns true if succeeded.

 unassigns <ENCODED_REGIONNAME>...
   A 'raw' unassign that can be used even during Master initialization.
   Skirts Coprocessors. Pass one or more encoded RegionNames:
   Skirts Coprocessors. Pass one or more encoded RegionNames:
   de00010733901a05f5a2a3a382e27dd4 is an example of what a random
   user-space encoded Region name looks like. For example:
     $ HBCK2 unassign 1588230740 de00010733901a05f5a2a3a382e27dd4
   Returns the pid of the created UnassignProcedure or -1 if none.

Pushed to branch-2.1+

Tested on cluster bypassing thousands of procedures at a time using this addtion.
