I want to do a script that decides where to move each region. For that I want to use the command:
move ERROR: wrong number of arguments (0 for 1) Here is some help for this command: Move a region. Optionally specify target regionserver else we choose one at random. NOTE: You pass the encoded region name, not the region name so this command is a little different to the others. The encoded region name is the hash suffix on region names: e.g. if the region name were TestTable,0094429456,1289497600452.527db22f95c8a9e0116f0cc13c680396. then the encoded region name portion is 527db22f95c8a9e0116f0cc13c680396 A server name is its host, port plus startcode. For example: host187.example.com,60020,1289493121758 Examples: hbase> move 'ENCODED_REGIONNAME' hbase> move 'ENCODED_REGIONNAME', 'SERVER_NAME'
For that I started to use the
hdfs dfs -du "/hbase/data/default_table_name/"
in order to find the region names.
However, I do not know, if there si a shell command to find out the startcode for each region (?).
