> - Till HDP 2.5, Ambari had used *'llapstatus'* command to query LLAP app
> status and has wrapped around the retry logic for how many times to query
> *'llapstatus'* command in order for LLAP app to reach *RUNNING_ALL* or
> *RUNNING* with 80 % containers Up.
> - With HDP 2.6, Hive has implemented a watch mode where Ambari doesnt need to
> have the retry logic in Ambari itself, and can use the *llapstatus* watch
> mode.
> Usage is as follows: (Information provided by [~prasanth_j])
> Following options are added to llap status tool
> *->* -w : Watch mode waits until all LLAP daemons are running or subset of
> the nodes are running (threshold can be specified via -r option) (Default
> wait until all nodes are running)
> *->*-r : When watch mode is enabled (-w), wait until the specified threshold
> of nodes are running (Default 1.0 which means 100% nodes are running)
> *->*-i : Amount of time in seconds to wait until subsequent status checks in
> watch mode (Default: 1sec)
> *->*-t : Exit watch mode if the desired state is not attained until the
> specified timeout (Default: 300sec)
> *Example usage:*
> {code}
> llapstatus -w -i 1 -t 300
> {code}
> The above command waits until all nodes are running with 1 second refresh
> rate and 300 second timeout (300 max attempts else fail).
> {code}
> llapstatus -w -r 0.8 -i 2 -t 150
> {code}
> The above command waits until 80% of the nodes are running with 2 second
> refresh rate and 150 second timeout (75 max attempts else fail).
> {code}
> llapstatus -w -r 0.8
> {code}
> Use without providing the -i and -t options (Defaults used).
