I implemented the HA admin tool, you can use it as follows:
- $TAJO_HOME/bin/tajo haadmin -formatHA
- $TAJO_HOME/bin/tajo haadmin -transitionToActive <target
tajo.master.umbilical-rpc.address>
- $TAJO_HOME/bin/tajo haadmin -transitionToBackup <target
tajo.master.umbilical-rpc.address>
- $TAJO_HOME/bin/tajo haadmin -getState <target
tajo.master.umbilical-rpc.address>
* Note
If you want to format HA state, you have to shutdown your tajo cluster
before formatting.
