HBase configuration files from master to slave synchronization

For the rsync used therein, see: basic use of rsync

#!/bin/bash#Rsyncs HBase files across all slaves. Must run on master. assumes#All files is located in/usr/localif["$#"!="2" ]; Then Echo"Usage: $ (basename $) <dir-name> <ln-name>"Echo"Example: $ (basename $) hbase-0.1 hbase"Exit1fi Src_path="/usr/local/$1/conf/regionservers"  forSrvinch$ (cat$SRC _path); DoEcho"sending command to $srv ..."; #–v represents complex output information;-A represents the permission save mode, which is equivalent to the-rlptgod parameter. Very fast saves almost all permission settings except for hard connections;-Z for Compression

-vaz--exclude= ' logs/* '/usr/local/$$srv:/usr/local/$srv"rm-fr /usr/local/$2; Ln-s/usr/local/$1/usr/local/$2""done. "

The same function, the following simple

 #  !/bin/bash  #   Rsync ' s HBase config files across all region servers. Must  run on master.  for  srv in  $ (cat/usr/local/hbase/conf/ Regionservers); do   echo   " sending command to $srv ...   "  

#  $srv:/usr/local/hadoop/$srv:/usr/local/hbase/"  Done. "
