Take single table snapshot

Usage: bash take_snapshot.sh <hbase_table_name>

Table all table snapshot

There are two ways to snapshot all tables.

  1. fast mode With the fast mode, a file with the command list is generated. The file is then passed to hbase shell. In this case, error handling is not possible in the event of a snapshot failure.

    Usage: bash take_snapshot.sh allfast

  2. slow mode
    In slow mode, the command is launched for each table with a separate shell. If a command fails, the script ends. This is a very slow process, as hbase shell has to be re-launched for each table.

    Usage: bash take_snapshot.sh allslow

Take multi table snapshot

For snapshot of multiple tables. Simply prepare a file (for example table.txt) containing the table list you want to take the snapshot and pass the complete path of file to the script.

Usage: bash take_snapshot.sh multislow /file/tables/list/tables.txt Usage: bash take_snapshot.sh multifast /file/tables/list/tables.txt

Generate file with tables list
